 * On startup, I see this error: “Php GD Extension or libavif is not installed/enabled.
   Please contact the server admin!” I have Ubuntu 22.04 installed on my server.
   I understand that this system comes with the libavif-dev package. That is, the
   package is installed, but the plugin doesn’t see it.

 * Hi,
   Thanks for the question. Can you please run a PHP script on the same server
   with the following code and share the output here?
 * ‘ print_r(gd_info()); ‘
 * 
   So I can have a better understanding of the issue you are currently facing.

 * Now the plugin can work without GD or libavif if ImageMagick ver 7.0.25 is present
   in the server.

 * Thank you very much! I will try to install ImageMagick.
   However, after updating
   the plugin I encountered this error. I had to remove the plugin for a while until
   the critical error is resolved.

   Avif express plugin again, but a critical error occurs immediately after activation.

 * Hi Pressport, 
   Yes, it now use Image Magic ver >= 7.0.25 as a fallback for **
   libavif**. Many users/servers facing the same issue even without this plugin.
   Managing server-related stuff is beyond the scope of this plugin. The plugin 
   just checks if the image magic version is above 7.0.25 or **libavif** is installed
   or not via Php script. If you have any specific issue, please mention it. So 
   I can have total exposure to the issue. Thanks for your comment. Happy to help
 * Regards,
   Pijush G.
