I am using Moodle (3.7) and can create an assignment link without any problems. I can also upload different file types to moodle pages without a problem.
However when I log in as a student and try to submit a file to an assignment link,I get the following error message:
There are some similar queries on this issue from a few years ago which have gone unanswered.
I have worked through the solutions presented (such as checking the settings etc.) but have had no luck in getting the assigment link to allow the selecting of a file.
