Hello,
I've a very strange issue.
After a normal upgrade from 3.5+ to the latest 3.6.3 Moodle version, now i cannot login. I always get this message "Error reading from database", as shown in attached picture.
I've made the upgrade using admin, all requirements were green, it updated all modules without any error and, before i've logged out (normaly), everything was working properly.
I didn't change anything after that, but now i can't loggin again.
I've enable debug from config.php (because i cannot access moodle admin interface) but there isn't any relevant errors.
My database was already in utf8mb4 format and my config.php matches that.
The strange thing is that withou loggin, all site information, courses and everything else shows properly.
Any help, please?
PS - This is the only warnigs that i have in frontpage, when i enable debugging:
