Installation and server related problems

Hi there,

I've been using H5P for a while now and all was well until we moved to a new hosting company. The shortcodes stopped working and we we're getting 503 errors. The hosting company has been super in helping us solve the issue so they turned up all resources for us because 503 normally means there aren't sufficient resources. But even after that as soon as I add a shortcode in an empty 'regular' post....the 503 error appears. It seems something is wrong with the plugin because as soon as we deactivate the plugin, the 503 error doesn't occur.

The website software

I am trying to add H5p interactive content to my moodle site as follows.

• Go to a course I created.
• Choose "Add an activity or resource".
• Choose "H5P Interactive Content". 
• From the "H5Phub: Select content type", I choose any of the available content (e.g. Interactive video) by clicking "Get".
• Click "Install".

The "H5Phub: Select content type" section disappears and I get the following error in the console:

TypeError: Cannot read properties of undefined (reading 'libraries')

I am succesfully using the WordPress H5P plugin on a domain that many students are using. I have just set up a new WordPress site in a subdomain of the same shared hosting server and installed the H5P plugin - my plan being to separate the training that uses H5P from the main (more corporate) website.

My problem is that when I try to Add content, all I get is a "Before you start' message at the top of an otherwise blank screen.
