Installation and server related problems

Dear all,

On my WordPress site I have created some h5p quizzes I’d like to embed to other pages outside the site domain. Other users tell me that this is not a problem at all, but on my pages I get the error message that the origin/source website has declined the access. I tried embedding the code on one of my other WordPress pages, but get the same error message. I've checked the plugin settings and also tried to grant access by changing the .htaccess file by adding

Header always unset X-Frame-Options

Using Moodle v3.9, mod_h5pactivity version 2020061500, PHP v7.4.33.
When I add new H5P activity into a course, it results http 500 error in Moodle v3.9.

After checking webserver logs, I see the following error:
PHP Fatal error:  Class core_h5p\\file_storage contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (H5PFileStorage::deleteLibrary) in /srv/www/moodle/htdocs/h5p/classes/file_storage.php on line 37, referer: https://mymoodle/course/view.php?id=123

Hi all,

I'm running a new AWS EC2 Bitnami Moodle server. The server is running perfectly until I attempt to create a new H5P activity which crashes the server. Once I get the server back online, I am often able to create the activity without the server crashing however often the process of editing the H5P activity will crash the server again.

I'm only running a T2.Micro server, perhaps scaling to a T2.Small will help. It's a 50GB partition with 38GB free.
