 * After uninstalling a plugin I have several tables in the database, which are 
   no longer needed. e.g.
 * Fus41RhR5_ppress_forms
    Known plugins that use this table name: wp-user-avatar[
   not installed]
 * Fus41RhR5_ppress_formsmeta
    Known plugins that use this table name: wp-user-avatar[
   not installed]
 * Fus41RhR5_ppress_meta_data
    Known plugins that use this table name: wp-user-avatar[
   not installed]
 * Clicking on the remove button at first seems to delete them but after refreshing
   the page the tables are still there!
 * Does this functionality in the plugin not work anymore?

 * [@supertrooper2](https://wordpress.org/support/users/supertrooper2/) Yes it should
   work as expected, Could you please check phpMyAdmin if the tables are listed 
   there, if yes, could you please try to repair the tables and then try to delete
   the tables from WP-Optimize and check if it gets deleted?

 * [@bornforphp](https://wordpress.org/support/users/bornforphp/) Hi Harshad
 * The 3 tables are not actually in the PHPMyAdmin table, so I don’t understand 
   why WP Optimize includes them in the list?
 * Another anomaly I have found is that there are 37 MyISAM tables listed in both
   the WP Optimize and PHPMyAdmin lists. All other tables are InnoDB.
 * I have clicked the “convert to InnoDB” buttons in the WP Optimize list, get a
   tick but after refreshing the page nothing has changed.
 * Please advise how to resolve this issue.

 * [@supertrooper2](https://wordpress.org/support/users/supertrooper2/) I’ll report
   this to our development team for further investigation.
