The progress of bulk optimizion runs for hours (12) but it only optimize a few of images. I refreshed the page so the optimizaion tool continue is optimizaion, but ptimize once again just few images. It looks that i s running but isn’t so (or maybe is only the counter that doesn`t upadete live?)
The second problem is that if i try to smush manually from the emdia library more of images aren`t supported; Invalid file format. Only PNG, JPEG, and GIF files are supported. But they are norma JPG file that in other case the plugin smush normally. So i think is not the file format.
