Installation and server related problems

Hello.

I am using WordPress 5.4.2 with verison 1.15 of the H5P plugin. When using WordPress I am on Firefox desktop version 77.

Using Firefox and Chrome, I have tried to add a new H5P activity. I can go through the steps to put together an activity, but when I press 'Create' after a while, I eventually get a page saying 'The connection was reset'. I have tried Drag and Drop, Text Drag and Drop and both activities have this problem.

HI

We have been having an issue with the wordpress plugin - throwing up this error:

Hello Everyone, 

I read a lot about this error, but I can't find the solution. 

Every time when I load the course presentation editor i got errors. 

The hit on F12 from the keyboard shows a lot of rules with "ERR 508 aborted"

I'm using Moodle 3.8.3 with the H5P plugin installed. 
The libraries are updated
The cache is clear

I tried some solutions like the permission ( i read in a topic ) to 777 
Updated the library 
Update the editor with the arrow box (plugin) to update.
