 * Hello guys. I need a step by step uninstall guide to delete a failed install 
   of your plugin and do a clean install.
 * I found that deleting this folder: “wp-content/uploads/wpo”, these tables: tm_tasks,
   tm_taskmeta, and these options at wp_options is not enough:
 * wpo_minify_config
    wpo_update_version wp-optimize-installed-for wp-optimize-schedule
   wp-optimize-last-optimized wp-optimize-schedule-type wp-optimize-retention-enabled
   wp-optimize-retention-period wp-optimize-enable-admin-menu wp-optimize-total-
   cleaned wp-optimize-auto wp-optimize-settings wp-optimize-webp_converters
 * What else should I delete to make a clean install?
    Thanks in advance.

 * BTW, this is the PHP error I’m getting. It is using PHP 7.4 like other of my 
   sites, but only this one got this:
 *     ```
       PHP Fatal error:  Uncaught Error: Class 'HtaccessCapabilityTester\Testers\HeaderSetTester' not found in /home/username/public_html/wp-content/plugins/wp-optimize/vendor/rosell-dk/htaccess-capability-tester/src/HtaccessCapabilityTester.php:180

 * [@kent-brockman](https://wordpress.org/support/users/kent-brockman/) Yes tm_tasks,
   tm_taskmeta are WP-Optimize tables its fine to remove the the tables.
 * Other than that if you have un-oinstalled the WP-Optimize plugin you can remove
   the folders from wp-content/uploads/wpo folder and wp-content/wpo-cache folder.
