 * I used to use POSTX Pro plugin but I don’t use it anymore. Despite deleting the
   plugin and all the data, it still automatically generates thumbnails for me (
   I assume the classes are from you) See below
 * s:5:”width”;i:150;s:6:”height”;i:113;s:9:”mime-type”;s:10:”image/webp”;s:8:”filesize”;
   i:4260;}s:12:”medium_large”;a:5:{s:4:”file”;s:25:”podhajska-11-768×576.webp”;
   
   s:5:”width”;i:768;s:6:”height”;i:576;s:9:”mime-type”;s:10:”image/webp”;s:8:”filesize”;
   i:55128;}s:11:”hd_qu_size2″;a:5:{s:4:”file”;s:25:”podhajska-11-400×400.webp”;
 * I don’t use thumbnails of this size at all anymore and they still overwhelm my
   database and space. How do I turn off (or cancel) the automatic generation of
   these thumbnails?
 * Before installing your plugin they were not generated but after installing your
   plagin they are still being generated.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fautomatic-thumbnail-generation-2%2F%3Foutput_format%3Dmd&locale=en_US)

 * While it’s unusual for thumbnail generation to continue after complete plugin
   removal, there are a few potential explanations:
 * Cached Data: Your web server or browser might still have cached data related 
   to the plugin, which could be triggering the thumbnail generation. To address
   this, please try the following:
 * Clear Browser Cache: Clear the cache and cookies in your web browser.
   Check Web
   Server Cache: If you have access to your web server’s configuration, ensure that
   the cache is cleared or set to expire regularly.
 * Search in your database related to postX – ultp , ultimate post . if have any
   delete that.
 * Final : Check clearly if those are coming from other pluigns.

 * I have stop using PostX Pro a year ago, it is not cache problem. We found several
   postmeta with ultp prefix after. where everywhere in database is this generating
   saved? options? posts? postsmeta? or some hooks in code?

 * Yes, even if you delete a plugin from your WordPress website, its data may still
   remain in the database. You may need to delete those manually.
