Using moodle 2.6 and I get the following error when I click "add new attempt based on previous submission". a required parameter (sesskey) was missing.
Any pointers would be appreciated. I have "updated" all assignments using upgrade tool but this error has only come up since I upgraded to 2.6
Thank you for testing and identify that error. Awesome.
I'm not familiar with this testing environment but to test do I just grab the new text from github for those 3 files edited and overwrite in mine?
Or else wait for the next update which I think is weekly.
