I upgraded Moodle to what I thought was the most recent version of 3.9 recently, and the site has worked fine for weeks.
I checked my server environment and somehow I am running 4.0dev on this production site.
I do manual upgrades by hand and I absolutely know that I would have seen the 4.0 in the WGET call. I feel like I downloaded a mislabeled file somehow.
At any rate, it's my fault and by now my backups all have the 4.0dev version. I tried a clever trick and tried to just install the files back for 3.9 but Moodle complained that the database was created by a newer version of Moodle.
What are my options here? Here are the things I have thought of:
1. Update 4.0dev to latest version, and hope that it fixes that issue and then basically stay totally hands of the site until I can figure out a more robust fix.
2. Export the courses and users and rebuild the Moodle installation on 3.9 or 3.10.
I would appreciate any and all feedback. Yes, I know backups are important, yes I had them, many of them, but its been two weeks and they all have 4.0dev on them now. Totally my fault, but I need to figure something out!
