I am using Moodle version 3.9.2. I want to change the course image for
one of my courses. I'm sure I've done this before with no issues. However,
today I opened the course, enabled "Edit settings", then simply tried
to upload the new icon for my course using File Picker > Upload a file, which I'm sure I've successfully done before. I can select the new icon, however, upon clicking "Save and
return", the Edit settings screen remains with the following
error message: "You must not attach more than 1 files here" seen in the tiny red type in image below. I know I can change the number of icons in an admin setting, but I don't need more than one icon.
All I'm trying to do is replace the current course image icon with a new icon. I am unable to update or delete the current icon. I can see the icon
that is on the server, however there's no edit, replace, or delete option.
When I click on the customer service icon (as seen above) I get the screen seen
below. However, I am still unable to edit or delete the file.
Please assist. Thank you.
