I created a course on my home install of Adapt AT - framework version 2.2.5 and AT version 0.5.0. Mac OSX if that matters.
I tried to import it to our install of Adapt AT at work, which uses the same framework and AT version. We run Windows 10 at work.
Now I'm getting an error when I try to import any course into our work instance of Adapt AT - including courses that have been created and exported only from the work AT.
The error is 'Course import failed, internal server error.'
