After removal
- Test public pages, admin screens, login, forms and search.

- Confirm important URLs and canonical tags.
- Scan for leftover unexpected files and accounts when security was involved.
- Remove unused database data only after the rollback period and a separate backup.
Frequently asked questions
Does deleting a plugin remove all of its database data?
Not necessarily. Plugins vary: some leave settings or custom tables, while others offer uninstall routines. Review the specific code and backup before cleaning data.
