unabletocopy on wordpress

Hello, team,

I have a huge problem! All my activities have stopped working and show blank on my website. I'm not sure when it started. I have updated all the libraries and installed all the updates, and it's still not working. I've attached screenshots of what I'm seeing.

I can see the content in the h5p list, but when I click the title, it's blank. When I click edit, I'm able to see all the activities and content is there, I'm able to edit and make changes, but when I press update, it gives me the error "unabletocopy". If I click edit again, the changes have been made.

I'm using WordPress version 6.9.1;

It's happening on all browsers I've tried;

it's happening on mobile and desktop;

H5P plugin version 1.17.1;

All content types that I use, and I mostly use interactive book, single choice set, drag the words, drag the images, dialogues and accordion;

Forgive me, I don't know how to check the errors;

Screenshots are attached;

I removed the plugin Jetpack Boost recently and installed ShortPixel;

No changes to the browsers that I'm aware of;

Please help! How can I fix this?

Here is an example of post where I have an h5p activity and it's just blank where it says "test your comprehension" https://thesoundsofportuguese.com/quem-e-quem-patreon/

Thank you so much in advance.

I am sorry to hear that you

I am sorry to hear that you are running into trouble.

You're using plugin version 1.17.1 is most likely the answer. It's buggy and introduces folder paths that it has never used before. That then may cause trouble with copying folders which results in the "unabletocopy" message.

You will find some more information about this issue at https://chaos.social/@otacke/116137501176248197.

Please note that I don't know when H5P Group is going to fix this issue, as I am neither affiliated with or endorsed by H5P Group.

Cheers,
Oliver

Hi All,

I am checking with the devs regarding the recent issues with the plugins. However, they are already on their weekends so I won't be able to provide any information until next week.

Patched the file, renamed

Patched the file, renamed folders, removed cache files, made sure the browser cache does not serve an old version?

Works perfectly fine, yes.

Around 400 h5p files not usable

We are facing the exact same issue and can confirm that this is not an isolated case.

After updating, several core content types are now completely broken on our WordPress installation:

Page
Interactive Video
Course Presentation
Drag and Drop
Fill in the Blanks

They either show blank on the frontend or fail during update with errors like “unabletocopy”.

This affects around 400 H5P activities on our platform. At the moment, they are not usable at all, which is causing significant disruption and frustration among our users. We rely on H5P for active course delivery, so this is a critical issue for us.

Restoring a backup would only be a temporary workaround and not a real solution — especially since we would lose recent content changes and risk running into the same issue again with future updates.

Is there a reliable fix or repair procedure (e.g. filesystem permissions reset, library path correction, content re-save script, CLI repair, database adjustment, etc.) that allows us to restore functionality without rolling back the entire site?
