Which template did you switch too? I've tried all the installed ones and get the same problem. The template has not changed from the development site which worked before I migrated with Akeeba.
Thanks Dimas. Here's a strange one which might help someone else.
I uploaded a different template as suggested
Made sure all menu items were set to default
Checked and I could alter the details such as group image from the front
As you suggested it worked
Switched back to the original template
It now works with the original template
