 * Hi
    The latest releases of the plugin can’t create thumbnails on my server. Last
   working version is 1.8.18 which is installed now. The system is running divi,
   php 7.4 on a nginx server. What could cause this problem. Kind regards Morten

 * How can you tell the thumbs cannot Be created? Are you getting the thumbnail 
   generation alert in the admin?

 * Hi bradvin. Yes that is correct and I have tried the various recommendations 
   to solve this problem ie deleting cache, override thumbnail test etc. During 
   speedtests I can also see that the plugin serves full size images instead.

 * It’s strange that a previous version works but not the latest, as the code for
   thumb generation has not changed as far as I can remember since the plugin was
   created.
 * I will have to look at the code for 1.8.18 and compare to the latest to see what
   has changed

 * Thanx. Let me know if there’s any tests you would like me to try. The website
   address is [http://www.stonehenge.co.za](http://www.stonehenge.co.za).

 * I compared the code between the 2 versions, and there are a few changes, but 
   nothing that should be causing the thumbs to not be generated.
 * Do you have a staging site available? If so, please can you update to the latest
   version and then goto the Settings page and under the images tab run the tests,
   so see what the exact error is.

 * Hi Brad
 * I have created a staging site and updated the plugin to the most recent version.
   There doesn’t seem to be any problems running it in the staging environment. 
   The built caching on the server is off by default on the staging site. Could 
   this be the problem?
 * Kind regards

 * hi [@mortenchr](https://wordpress.org/support/users/mortenchr/)
 * There must be some config that is diff btw the live and staging, that is causing
   the problem.
 * Another user recently had a similar issue. They had imagick and GD PHP libraries
   on their server. Imagick is used by default, but there is an advanced setting
   on FooGallery settings where you can Force GD. If you have the same scenario,
   perhaps you can try this?

 * Hi bradvin
    I have updated to wp 5.5.1 and foogallery 1.9.34. This seems to have
   fixed it.
