 * Hi! First of all, thank you for offering this plugin for free to the community!
 * Second, it does not activate in my instance. No error message, just no action.
   What i notice:
    - Installation and activation: fine. But in the Settings->Media dialogue, the“
      test” does not show.
    - Upload does work (no error messages), but wordpress returns “cannot be displayed”,
      and display window stays blank.
    - First, I thought that it was missing imageMagick, but it’s activated.
    - Could there be a collision with the siteground “speed optimizer” plugin (v.
      7.7.0)? This plugin manages media file sizes, generates thumbnails and .webm
      optimized output files.
    - Or “Enable Media Replace” (v.4.15)? This plugin enables direct replacement
      of a media file with another without changing every instance.
 * My versions etc.:
    - PHP: 8.0.30
    - wordpres: 6.6.2
    - HEIC support: 2.1.3
    - imagick version: 3.7.0
    - Anything else? PHPinfo() is 8 pages long and might contain vulnerability issues–
      I won’t publish this 🙂
 * Many thanks for your help,
 * Claus

 * I have precisely the same situation as described by the OP (but my PHP version
   is higher), 
   Siteground, WordPress 6.6.2PHP 8.3, HEIC support: 2.1.3I am able
   to (and have) activated imageMagick.
 * HEIC Support plugin shows as ‘activated’, I get the headings showing (as below)
   but none of the actual control settings are showing.
 * HEIC Support 
   Control how .heic images are handled during uploads.Test
 * Also thanks for this plug-in – if we can work out what’s stopping it working 
   it will be an amazing solution to a specific issue.

 * [@clausfaber](https://wordpress.org/support/users/clausfaber/) it looks like 
   the issue will become solved in WP 6.7 release which is due in a couple of days–

 * Same problem. All I see is:
   HEIC SupportControl how .heic images are handled 
   during uploads.Test
 * But none of the actual control settings are showing.
 * Siteground,
   WordPress 6.7.1,PHP 8.2.27,HEIC support: Plugin 2.1.3,Imagick version:
   3.7.0,ImageMagick 7.1.1-39 1809,ImageMagick Engine Plugin 1.7.13,Disable Media
   Pages Plugin 3.1.3,Enable Media Replace 4.1.5,Speed Optimizer 7.7.2
 * When I upload an .heic file, there is no image to edit. No error message is generated.
 * Hoping for a solution and will keep trying this and that.
 * Thank you,
 * Barry Brunning
