H5P Mods no longer working after update


I am using H5P on Wordpress 5.9.6 in combination with the H5P Mods plugin to tweek some css.

I updated H5P 1.10.0 to 1.10.2 and from that moment on the css tweeks are no longer active (I did not chage the location or name of the custom-h5p-styling.css file). I use Firefox and Chrome, both show the same problem.

Also re-installing H5P 1.10.0 does not reactivate the css tweeks. I see on the page of a H5P exercise that the file custom-h5p-styling.css is loaded (


, but nothing is activated, see for example my page https://www.pent2.nl/pad-3/?pen=1&blok=1&blok_volgnummer=5

On that example, .h5p-audio-inner .h5p-audio-minimal-button is set/modified to: {   font-size: 1.8em !important;}

Do I need to reactivate somehow the H5P Mods plugin after updating H5P, or is there another reason why this could go wrong after an update of H5P?

To me, it looks like it's working like it should.
If you don't see it try it in another browser, clear your cache or even try "incognito mode".

After updating to H5P plugin on Wordpress to 1.11.0 I can no longer create or edit course prsentation types. I get this error in my console (screenshot atatched):

Failed to load resource: the server responded with a status of 404 (Not Found)

h5peditor.js?ver=1.11.0:111 Error while loading scripts: Event

script.onerror @ h5peditor.js?ver=1.11.0:111


After disabling the H5P Mods plugin it works as normal, but all my mods are gone :(.
