Hello, Sami.

If you upgrade your OS to a newer version, maybe you can`t change format.

Yes - me too.

Same version of Chrome and on both Moodle 3.9 and 3.11  

We're not seeing it on all sites for some weird reason. We spent a good chunk of yesterday trying to to work out what the dependencies are. Some sites worked when changing theme - some didn't.

I don't use Windows but the word is that whatever it is effects Edge as well.

In Chrome on a Mac it's just an "Error 11" but I assume it's the same thing.  Perfectly fine in Firefox and Safari.

Hi, we have the same problem in Chrome/Edge and it is funky. We have two of our custom themes and we get this error just in one theme and only using teacher role. If I change the course format with admin account there is not problem. This happens on our Moodle 3.11 and 3.9 installations. On Moodle 3.7 we get this error with admin account also.

Yeh - one one of our sites we get the problem with a boost-based custom theme but not with vanilla Boost. On the other site (which only has Boost) Boost shows the failure. Weird.

This seems to be affecting browser that use some version of the Chromium rendering engine, which is of course Chrome, but also Edge and Brave too (and there are probably others).

We have the same problem. I think it might be a problem with browser engine of Edge/Chrome V93. I did some tests with Chrome V94 beta - the problem no longer occurs there.

I have the same version of Chrome and using Windows 10 pro 21H1, Moodle 3.9.4, uninstalling chrome and installing an old version (90.0.4430.72) did the trick for me

We checked with Chrome 94 (Beta) and that works fine.

Setting the following code on theme custom CSS, fix the problem:

fieldset:target::before
{ content: unset; }

Also, seems this workaround is only required for Chrome 93, Chrome 94 (to be released on Sept 21 2021 fix this bug)
