Code 403 when trying to add new column

Hello @MemriseSupport :blush:

I was added as a contributor to the Luxembourgish course for English Speakers and I tried to add images to the course via web version on Windows 10 Enterprise (version 21H2).

Actions: → Databases → Add column → Image → Add → Nothing is happening (network shows 2 errors). See screenshot attached.

Please advise :roll_eyes:
