Hi @jeancarr3
Like many plugins, we do not delete the database tables when you uninstall WP RSS Aggregator.
This helps when you deactivate a plugin temporarily while troubleshooting and would like all the data back after reactivating the plugin.
If you would like to permanently delete the database tables, you can do so manually if you are comfortable with administering the database from your site’s cPanel or database admin tool. You could also use a third party plugin that helps remove database tables no longer in use.
Please ensure you have a full backup of your site and restore point ready, just in case something goes wrong and you have to roll back the site to the last working version.
