Forbidden message accordion activity Moodle

Hi all,

We are trying to create some H5P-activities in Moodle 3.3.1+. We tried making a accordion activity, but after adding the content and pressing on Save, we got an error (Forbidden. You don't have permission to access /course/modedit.php on this server.). It looks like a time-out, but that doesn't seem likely to us. The last changes we made also disappeared.

In this specific case we made an accordion-activity, but it also happened with other activities. Has anybody experienced the same? Is there a solution to this problem?

Hi RoyElevate,

Where there any recent changes in Moodle or your host server? Please check your PHP log for any errors and check your browser's console log for any errors.

Make sure that you have configured PHP properly with all the extensions listed in
