      I got a global error message "Failed to unserialise data from file. Either failed to read, or failed to write". I checked and the problem was on moodle/cache/stores/file/lib.php. I manage to log back into the site by clearing manually moodle_data/cache folder. I checked the log files and i see this notice keep coming up PHP Notice: Undefined variable: data in /var/eclass/cache/stores/file/lib.php on line 367
