@imagely re NextGEN Gallery (free) Version 3.37
gd is enabled in our settings in PHP version 8.1 but there is still the error message:
NextGen Gallery requires the following PHP extensions to function correctly. Please contact your hosting provider or systems admin and ask them for assistance:
GD is required for generating image thumbnails, resizing images, and generating watermarks
The update also broke Download Manager 2.9.1 with some files not displaying, some only showing shortcode and others showing correctly.
