I just removed all of these extensions (again) and reinstalled in the listed order.
I can now open the menu writer.
Why is it that every time a new extension is released all of the old extensions need to be deleted??? A very frustrating time waster.
I simply deleted eCart 5.0.3 and installed 5.0.4 and then I had this issue. Should I not have been able to simply delete 5.0.3 and then install 5.0.4 without affecting these other extensions?????
