 * Hi, after wordpress 5.4 update, thumbnails in the back office foogallery section
   aren’t shown anymore (there are only grey squares) but pictures are still displayed
   in the front office.
 * would a plugin update be possible quickly for compatibility?
 * Thanks

 * Hi [@angrafik](https://wordpress.org/support/users/angrafik/)
 * We added a lazyload function into the gallery admin which improves performance
   for very large galleries.
 * I have tested this in 5.4 and it works as expected, so there could be a conflict
   in your setup. When editing a gallery, do you notice any javascript errors in
   the dev tools console? If so, please paste the details here

 * Please also make sure you clear your browser cache, to make sure you have the
   latest javascript running
