I updated to the 3.10.1 and now all fields for the theme Klass, Boost, Fordham --- all themes I have --- cannot load a photo. It is a perpetual spin where I should be able to upload an image. The icons to list images such as the 3 lines, folder, etc. all resolve to a # as well.
It looks like this site has been upgraded using Softaculous. Softaculous is notorious for breaking sites on upgrade because it leaves behind files from the previous Moodle version, this is contrary to the instructions ("Do NOT copy new files over the old files").
The fix is to ensure only the source code files for the current Moodle version are present, try these steps but substitute 3.10.1 for 3.9.2. Some people (one, two) have suggested that you can open a support ticket with Softaculous and they'll fix the upgrade.
If you get stuck, just ask. Screenshots can help us understand what you're seeing.
Thanks for the assistance and have a great day!
If I explained that badly my apologies, "substitute 3.10.1 for 3.9.2" – I meant substitute the version referred to in the steps.
But I'm glad you've got it working.
Have a great, safe weekend!
