The WP Staging plugin is commonly used to create a staging site if your host does not provide one-click staging site creation.
If you no longer need one of the created staging sites, then you can delete it from the UI of the WP Staging plugins.
Uninstalling the WP Staging plugin would not delete any staging sites or delete the created database tables for the staging site. Even after deleting a staging site, there might be some left-over database tables related to WP Staging.
The Left-over WP Staging database table could be due to a cloning process being interrupted.
If you find any left-over database tables from the WP Staging plugin after the delete process of a staging site has been run, then it is recommended to delete those manually.
WP Staging database tables for the staging site would use the following table prefixes;
wpstg0_
wpstg1_
wpstg2_
wpstgbak_
Most hosts provide the phpMyAdmin application, which can be used to easily delete all of the WP Staging database tables using the UI of the application or by running a SQL query to delete those.
The SQL query to run in phpMyAdmin would be;
SELECT CONCAT('DROP TABLE ', TABLE_SCHEMA, '.', TABLE_NAME, ';')
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME LIKE 'wpstg0_%'
or TABLE_NAME LIKE 'wpstgtmp_%'
or TABLE_NAME LIKE 'wpstg0_%'
or TABLE_NAME LIKE 'wpstg1_%'
or TABLE_NAME LIKE 'wpstg2_%'
or TABLE_NAME LIKE 'wpstg3_%'
or TABLE_NAME LIKE 'wpstg4_%'
or TABLE_NAME LIKE 'wpstg5_%'
or TABLE_NAME LIKE 'wpstg6_%'
or TABLE_NAME LIKE 'wpstg7_%'
or TABLE_NAME LIKE 'wpstg8_%'
or TABLE_NAME LIKE 'wpstg9_%'
or TABLE_NAME LIKE 'wpstg10_%'
or TABLE_NAME LIKE 'wpstg11_%'
or TABLE_NAME LIKE 'wpstg12_%'
or TABLE_NAME LIKE 'wpstg13_%'
or TABLE_NAME LIKE 'wpstg14_%'
Deleting staging sites in the WP Staging plugin would help keep your site’s database free of bloat.
