Plugin will not keep watermark checked. Once checked it will stay for about 2 seconds then go away. Will no longer watermark. Will not un-watermark images already watermarked.
Opacity never worked. Neither did sizing of watermark.
Never found out what else didn’t work due to start of failure to watermark. Have tried all the normal fixes like turning plugins off and on, as well as updating everything.
Wordpress 4.8 but did same on earlier version.
Plug in menus offer needed options. Would be nice if they worked.
