Hello community,

I'm running into an issue with Moodle 4.0.1 and wanted to share so that we can brainstorm around.

Basically, my Moodle instance breaks up completely out of the blue due to an Ajax error that pops up with the message "Error updating user preference 'drawer-open-index' using ajax".

Has anyone here gone through the same issue? 

Looking forward for hearing your ideas.

Thanks,
Fabricio
