Gizmo,
I have the same problem as above with one major difference, like Pappy, I misunderstood what this box was for and I tried placing an HTML link to an image into the box. That gave me the same error but when I removed it, I still get the error and now I can not load ANYTHING including the control panel. Can you help?
I'm using 7.5.7
