Hi @geek
MySQL is reporting that your “sessions” table is entirely missing.
Given that you moved your OJS to another server, are you using same MySQL credentials? Did you create Database, Username and Password exactly like they were on your previous server?
If so, then database configuration in config.inc.php may be pointing to an empty database or something that’s not OJS, please double check it.
