Same with us. I manage a large and very busy funeral home site with multiple editors and users that log into the back-end. Drove me nuts because as admin I could see everything and they were calling saying they could not. Lots of plugins on the site, so I can’t deactivate all of them at once. Finally found the issue with WP Google Maps plugin. Deactivated and all users are working.
Please fix asap. The map is important for families and friends who attend the funerals and need directions.
