Definition
Error 1033 generally points to corruption of the .frm file for the table being queried. This can be caused by InnoDB reconfiguration, form file corruption, and permissions issued.
Sample
SELECT COUNT(*) FROM auth;
ERROR 1033 (HY000): Incorrect information in file: './auth/auth.frm'
Resolution
- Check that the permissions on /tmp/ allow for reading and writing by the mysql user.
- Stop MySQL, delete the ib_logfile0 and ib_logfile1 files from your MySQL datadir and start MySQL.
- Restore from a backup.
