 * Hi, I’m not sure if it’s because of a plugin update, but now uploading images
   in the media library and on the post pages doesn’t add watermarks anymore. Also,
   manually adding watermarks to various images doesn’t work. It shows the following
   error.
 * Watermark could not be applied to every selected image size. (failed: 0 processed,
   2 failed, 0 skipped)

 * I have a PHP file that converts images to WebP mounted on functions.php. After
   I tried disabling this feature, your watermark could be added normally. Can you
   tell me how I should modify this filter to work with your plugin? Thanks!
 * add_filter(‘wp_handle_upload’, ‘enhanced_webp_converter’);
   function enhanced_webp_converter(
   $upload) {….}
 * What I can confirm is that it used to work fine before. After the image was uploaded,
   it could be converted to webp and have a watermark added. But I haven’t tried
   whether the watermark can be removed; your ability to remove it depends on being
   able to find the original file.
