Is there any way we can move sessions to mysql from crushFTP.
Sessions as in Statistics?
You can change the DB being used in the preferences, stats config. Change the DB driver, DB URL, user, pass, etc.
If you do the Test DB on stats config, does it work?
What exact crush version is this?
Have you changed any of the queries? Or are they left at defaults?
Reset the stats config to defaults, reconfigure your SQL driver, URL, etc, test DB, restart CrushFTP, login, transfer a file, and logout.
