Hello Moodle Communities:
I need urgent help with this issue. I tried upgrading Moodle to the latest version. I put the site in maintenance mode and I started the upgrade. However, after the upgrade was finished, Moodle did not load. I had an alternate login page because I was using a plugin for accessing the website with a token from Google Authenticator, I commented out that alternate login page from the config.php and tried to login, I got to the sign in page, but when I signed it, I got blank page. I tried to downgrade to the previous Moodle folder, I got this error message: ERROR!!! The code you are using is OLDER than the version that made these databases!
The site has been down for two days and I am out of options. Please if you have any ideas or suggestions, please please let me know. I have got more than 500 users who cannot log into their courses.
