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. 

Hi there,

I just have a small question about H5P in Moodle. For example in the "Find the Words" activity. On my laptop the activity is quiet to big to work with it. On my computer with a 22-inch display I can use it without any problems. Is it posible in one way to resize all that stuff, like a fit-to-screen function?

All my activities are made directly in Moodle, not on the H5P website.

Thanks a lot to all :-)
