Under Tools > Diagnostics > Database Info, there are minor errors that all begin with “table cerber_sets’ doesn’t exist”
How do I fix this?
You can safely ignore those errors if you only saw them once, like right after activating WP Cerber for the first time or after restoring a website from a backup. Why can you ignore them? Because WP Cerber has a built-in mechanism to rebuild its database tables. You can also do it manually by clicking the Repair Cerber’s Tables button on the Diagnostic tab. Any missing tables will be recreated, and tables with outdated structures will be upgraded.
If you see such errors regularly, that’s usually a bad sign and may indicate a plugin conflict. For example, a maintenance plugin might accidentally delete WP Cerber’s tables during a ‘cleanup’ procedure.
