# Plugin Causes Featured Image Error on WordPress

 * Hi guys –
 * I found an error that this plugin is causing.
 * I found out this week that I could not add a featured image to any post or page
   in WordPress. Upon clicking “Set Featured Image”, the media library folder would
   open, and the first image would be a blank grey box, with no attributes at all.
   The blank image cannot be deleted, nor edited, and when you try to select any
   other image in the media library as the featured image, the window closes and
   no featured image will exist on the post or page.
 * I disabled every plugin on my site (36 of them) and tested each one, and the 
   cause if this plugin. Once this plugin is disabled, the featured image selector
   works again, and the fake grey image no longer exists. As soon as the plugin 
   is enabled, the image reappears and no featured image can ever again be set on
   a post or a page.

 * Dear [@seosupremacy](https://wordpress.org/support/users/seosupremacy/),
    I have
   the same problem on another website with other plugins. Our problem is with the
   template, but we can’t find it.
 * This problem seems to be very tricky to track,
    **could you be that kind to tell
   us what was the problem with your plugin and how did you solve ?**
 * Thank you

 * I solved,
    for future help and reference, I solved removing a 404 error on some
   missing images in the admin area, AND some “mixed content” error in the admin
   area (because website is in https and some of the files were loading in http).
 * Also I updated a few php files that were giving php errors,
    so give a check 
   on your logs.
