Sometimes even the best plugin wants to be uninstalled!
So, if you like to uninstall WP STAGING and remove all its data and settings completely, just follow the steps in this article.
Go to WP STAGING > Settings and select the option
Remove Data on Uninstall
If you also want to delete all staging sites, go to WP STAGING > Sites and use the DELETE button on every site listing entry:
After that, go to WordPress > Plugins and deactivate and uninstall WP STAGING
There may be possible that certain tables are still available in the database WP STAGING created for backup purposes.
They begin with wpstgbak_ or wpstgtmp_
You can remove all of them completely by using PHPMyAdmin or any other database administration tool you choose. (We love adminer!)
