Since then, I haven't been able to manually add an order or edit an order. The problem always happens at the adding product stage and I get the message:
I am logged in as Top Administrator, I have created a new Top Administrator log in and asked my host to reset all file permissions. None of these have worked.You do not have permission to access this page, please refer to your system administrator.
Is there something else my host needs to enable or disable on the server to fix this problem?
Thanks for any help!
