FAQ.KG
-
Does this delete important data?
-
No — the plugin only targets metadata that is clearly empty, unused, or orphaned.
If backup is enabled, you can restore deleted rows at any time. -
Is there a preview mode?
-
Yes. Preview mode allows you to see exactly which meta rows are considered empty before removing anything.
-
Does this support ACF fields?
-
Yes! It includes a dedicated ACF cleanup engine that uses pattern rules to identify real orphan fields.
-
Can I add my own patterns?
-
Absolutely. You can add or remove SQL LIKE patterns directly from the admin panel.
-
Does it work on multisite?
-
Yes, it works on standard and multisite installations. Cleanup runs per site.
-
Will this improve my website speed?
-
Yes — removing thousands of empty meta rows reduces database size and speeds up queries.
-
What if I delete something by mistake?
-
If backups are enabled, deleted metadata is stored in a dedicated table so you can manually restore it via phpMyAdmin.
-
How safe is the scheduled cleanup?
-
Very safe — it follows the same rules as manual cleanup, including retention rules and backups.
