Bugs in content types

SOLVED
The bug was not in H5P, but in Imunify360 - some security-software on my web-hosts servers.
Imunify has now corrected the error and pushed updates to my webhost.
If others experience the same issue – try asking to Imunify360..

(Is there an "official" way of marking the bug report as solved?
I think the issue is relevant if someone encounters this issue, so deleting the post will not be good ... - or what?)

ORIGINAL POST:

In Course Presentation (CP) I get a 403-error when I click “Update” after I have copied elements in the presentation.

Platform and version number: Wordpress 6.4.3
PHP 8.1

Desktop

Browser:  Firefox

H5P plugin version: 1.15.7

H5P content type and version: trying to update Column 1.13.1 to suggested version 1.16.2

Any browser console errors:

Hello all,

We are not able to load the H5P editor in Moodle.

When we try to 1) create any new H5P activity, or 2) try to edit an existing activity; the editor doesn’t load and stucks on the message “Loading, please wait…” (please see the attached image).

Notes :

-We upgraded Moodle recently, and are now running Moodle 3.11.6. The issue started after that upgrade.
