And forgot to mention, it happens on a test profile page after adding profile image, an album with 2 images and trying add a small video clip. After seeing the error message, I deactivated all plugins but it didn’t go away.
I installed on a website I am setting up and decided to delete it as I was more happy with BuddyPress so I deleted the plug in but the link to GRA4 is still on my site. Anybody an idea for this beginner techie to get rid of it? See http://www.happinesz.com
