I'm having an issue with my Moodle installation. I have been running version 2.9.9 for the past couple of months on my Synology DS216play for several of the classes I teach. I've been trying to avoid updating past 2.9.9 since several of the question type plugins that I use have not yet been upgraded to be compatible.
My Synology was inadvertently set to auto-update its ''packages'' and so it downloaded and installed version 3.4.1 and now I am being prompted to with:
Your Moodle files have been changed, and you are about to automatically upgrade your server to this version:
3.4.1+ (Build: 20180118) (2017111301.01)
Once you do this you can not go back again. Please note that this process can take a long time.
Are you sure you want to upgrade this server to this version?
======While I would prefer not to update, I can't see anyway around it (suggestions welcome) since I and my students have completely lost access to our Moodle.
When I try to upgrade to the new version I'm given the error:
I've tried moving my current web/moodle and reinstalling 2.9.9 in the same place, but I get an error that my databases were created with a more recent version of the software.
I've also tried installing 3.0 and 3.4.1 in my web/moodle folder but I continue to get the error in the attached file.
Can anyone advise me on what I'm missing? Be it a step to sucessfully upgrade the database to 3.4.1 or (preferably) a way to recover my 2.9.9 installation?
