Hello Rafa. I saw this tracker issue which suggests it has been worked on and has recently been fixed https://tracker.moodle.org/browse/MDL-72316 in Moodle 3.10.8 and Moodle . These are due to be released next week if you are able to upgrade. Alternatively, since you made the SCORM course yourself, perhaps you could replace the SVG with a PNG?

Hello Przemek. As the docs are a wiki, you're welcome to edit them yourself. In the meantime I've added a note in the section on Badge details with Helen's suggestion about adding the course teacher's name to the badge description.

Hello there - I am about to move your post to the Installing and upgrading forum. Hold onto your hats

Why not make a course and have everyone on the site enrolled in it? Then add that link as a shortcut on the Dashboard.

Just to try to troubleshoot (it is a weird error) what happens when teachers try to add content to a course (and not site admins)? Teachers only have permissions within a course and it would be interesting to find out.
Also what are the URLs of those activities that appear in the main menu -are they actually related to the course where they were added?
