H5P Guides

Troubleshooting H5P errors

A guide for dealing with the most frequent problems met when setting up and administering the H5P plugin on your site.

We are continually updating H5P and fixing issues that we find or that are reported along the way. Before posting about an issue, please check the latest updates to see whether there is a fix for your issue. A list of recent updates can be found in the Release Overview page.

List of contents:

Unfulfilled H5P dependencies
Network communication issues
Other issues

Unfulfilled H5P Dependencies

The problems listed in this section must be handled by the system administrator

Your PHP version does not support ZipArchive

Your PHP installation does not support the ZipArchive extension, which is needed for H5P.

Your PHP version does not support mbstring

The mbstring PHP extension is not loaded. H5P need this to function properly

Network Communication Issues

The problems listed in this section must be handled by the system administrator. Several different messages may be displayed when an H5P site fails to communicate with h5p.org:

Failed fetching external data
Failed communicating with the H5P HUB
Failed registering site at H5P HUB
Got no content types from HUB

You should first verify your H5P site is able to communicate with h5p.org e.g. by using the ping command (run it on your server). If that fails, it might e.g be a problem with the server's DNS setup or it might be a firewall or similar blocking the traffic.

A common problem we see with Guzzle is that a required certificate is not present when using the HTTPS protocol.
You can usually solve this by adding a valid "cacert" to your server setup. See papi Joe's comment for more information.

Invalid H5Ps

The problems listed below are mainly relevant for developers, and can most probably be seen during the development phase

The file you uploaded is not a valid HTML5 Package (It does not have the .h5p file extension)

An h5p file has to have the .h5p file extension to be valid

Unable to unzip H5P file

The file you uploaded is not a valid HTML5 Package. The H5P file you were trying to use was not possible to unzip. It might be corrupt.

Invalid h5p.json file

The h5p.json file is either missing or it is not valid. It could be that the content you're uploading is using newer versions of H5P than what is installed on the site you're uploading content to. (If you're using H5P.com note that H5P.com is two weeks behind H5P.org)

Invalid content folder

The H5P is missing the mandatory content folder.

Invalid content.json file

Could not find or parse the content.json file

Library directory name mismatch

Library directory name must match machineName or machineName-majorVersion.minorVersion (from library.json)

Missing required library

A mandatory library is missing from your package

Missing library dependency

One of the library dependencies is missing

Invalid library name

The library name is not according to the specification

Invalid library.json file

The library.json file is missing/not readable, or the content is not according to the specification

Invalid semantics.json file

The semantics.json file is missing/not readable, or the content is not according to the specification

Invalid language file

A language file included is not following the specification

Missing file

A mandatory file is missing from the library

Missing required property in library.json

The library.json content is not following the specification

Illegal option in library.json

The library.json content is not following the specification

Other issues

A mix of issues that does not fit in the other categories.

API version unsupported

You are trying to install an H5P library which requires a newer version of the API. Please update the H5P module/plugin

Insecure file in H5P

There is a file in your H5P that is not allowed inside an H5P because of security

Failed creating H5P export file

H5P was unable to create the downloadable H5P file. Please check the file permissions

Save content failed

Something went wrong when writing the content to disk. Please check the file permissions

Bonjour, j'ai un problème et je ne sais pas comment faire pour effecuer la mise à jour du plugin ...

Voici le message que j'obtient lorsque j'essaye d'installer un paquet :

Hi blebar25,Are you updating

Hi blebar25,

Are you updating the plugin or are you updating a content type. If you are doing the later you need to update the plugin first for this to work.

The h5p moodle-installation only offers 4 content types and that is why I created the content in h5p.org. On the other hand, I did embed the content on a moodle-webpage activity, but I don't manage to upload.

Any hints? Thank you indeed!

Reporting and additional features and functionality's

I have not been successful in connecting my H5P to my LMS. Is there "How To" I can use to walk me through that process?

Thu, 03/05/2020 - 23:01

Hi Coach,Different LMSs

Hi Coach,

Different LMSs provides different features and ways to configure them to utilize H5Ps. If you can provide us which LMS you are using and what exactly do you need either the community can point you to a document or provide you with the steps.

Hello, I am trying to modify the ImagePair module for a specific purpose but I cannot understand the process of creating .h5p files well, I have seen the tutorials that I have but I have not been able to modify it, there is a video or some other resource that I can use to do it. thanks

Mon, 03/16/2020 - 17:14

Hi Julian,If you've read this

Hi Julian,

If you've read this documentation, I'm afraid there isn't any other resource available. Although we can use the forums to ask for assistance from the community. I suggest that you post your question there, you may want to include a screenshot of errors in your browser console as it would provide details on what is going on. Also you could give more details on what you are modifying and what code you added/removed/modified.

Where can I download the libraries?

I am in China and the update function does not work so I will need to download and install individual libraries, where can I download them?

Mon, 03/30/2020 - 11:57

Hi gibbywilson,THe libraries

Hi gibbywilson,

THe libraries can be located here. However it is a million times easier and faster if you just download the sample contents and upload them. By design H5P automatically updates the libraries if you upload a content that has a newer one. It would also make it faster if you start with the 'complex' content types such as Column, Course Presentation etc.

Upload problem: Validating h5p package failed

We have created some content on h5p.com. Now we would like to transfer this to our Wordpress-Homepage with H5P-Plugin (Version 1.15.0).

I downloaded the H5P file and tried to uploaded it to WordPress via the H5P upload option in the plugin. Then I get the error message

Validating h5p package failed.
Invalid data provided for licenseExtras in h5p.json
The main h5p.json file is not valid

In connection with this, I found that the version in h5p.org is always newer than that of h5p.com. But here it would be the other way around, i.e. transfer from h5p.com to h5p.org (or plug-in). Can it still be related to it? Do you have any other suggestions?

Thanks und best regards
Felix

Mon, 03/29/2021 - 19:27

Hi Felix,Which content type

Hi Felix,

Which content type are you trying to upload?

You are correct most of the time H5P.org has a newer version of content types compared to H5P.com this is to make sure that the updates are tested on a "real" environment before releasing them in H5P.com. However the plugins, Wordpress included are updated almost at the same time as H5P.org so this shouldn't be the issue.

Mon, 03/29/2021 - 21:25

Hi BV,thanks for your answer.

Hi BV,

thanks for your answer. The content type is Virtual Tour (360). It was created about two weeks ago on h5p.com, before I downloaded it and tried to upload.

Best regards
Felix

Tue, 03/30/2021 - 19:25

Hi Felix,Would you mind

Would you mind testing if you upload my test content. I was able to upload it in Wordpress with the same H5P version as you are using. If you can upload this test content I would suggest that you contact H5P.com support directly by following the instructions on this page.

When sending the e-mail I suggest that you include the link to your content.

Wed, 03/31/2021 - 10:26

Hi BV,I was able to upload

I was able to upload your test content in Wordpress without any problems. As suggested, I will now contact h5p.com support. Thank you for your support!

Missing required library H5PEditor.ColorSelector 1.2

Hi there, I recently installed the H5P plugin for my website on WordPress 5.7.2. When I tried to create content (Branching Scenario), I got the following error message and am unsure how to fix it.

Thu, 06/24/2021 - 19:06

Hi clarisse_p,

Can you try downloading this sample content and uploading the file into wordpress. You can check more details on how to import/export contents on this documentation.

Same issue

Hi BV52,

I am having the same issue as clarisse_p but when installing the package on a self-hosted Wordpress site. I've tried your suggestion of uploading the sample content but then get the same error with a slight variation to the last number (Missing required library H5PEditor.ColorSelector 1.3)

Thanks,
Will

Fri, 06/25/2021 - 11:05

Resolved

Hi clarisee_p / BV,

I've resolved this by first installing the Interactive Video part and then retrying the Branching Scenario part. I guess the former install the correct version of the Color Picker and then this stage was bypassed for the installation of the Branching Scenario part.

Best,
Will

Fri, 06/25/2021 - 18:52

Hi Will,Good to know you got

Hi Will,

Good to know you got it resolved and thank you for providing your solution. It is unusual however that the color picker was not included in the installation of Branching Scenario since IV should be part of the installation thus including the color picker.

H5PEditor.ColorSelector (1.2.6 >>> 1.3.0)

I had the exact same issue, but importing 'Interactive Video' didn't work for me, however after much Googling and experimenting here is my solution:

Force the ColorSelector library (1.2.6) to update by importing a new content type that isn't already installed. I used 'Image Hotspots' and downloaded the example from:

https://h5p.org/image-hotspots

This added the new version H5PEditor.ColorSelector (1.3.0)

N.B. I was unable to update this ColorSelector library via the 'H5P Hub' interface, an update option was never presented to me.

Unable to comment on other pages

When I try to comment on one of the H5P installation pages it says "log in or register to comment" - when I click the log in button it jumps to the top of the page.

When I log in via the top of the page I can see "my account", yet when I navigate away from this page I am logged out again and it says "log in" again.

Adding a h5p element into a lesson in Tutor LMS

I am confused.

I am trying to insert an h5p element into a lesson. I have two accounts.

As the admin, I can create h5p elements, which I see listed in the library, once they have been created. On the lesson page, I can see the "add h5p" button and when I click the button, this goes to my library, which I can choose from. No problem.

As a tutor, I see the "add h5p" button on the lesson page. But I cannot add any h5p element, not even to a library of h5p.

Is there a permission/setting I am missing?

Thanks.
