User roles

I am running version 3.58 and have problems with user roles and permissions. I installed the plugin in June 2021 and had no problems setting up a test product and test service when I was site administrator.

Now I cannot amend services as site administrator, technician, store manager or shop manager – error message is “sorry you cannot access this page”. I can only amend products if I use the ones in woocommerce and not repairbuddy itself.

As site administrator I cannot amend my own role to anything else – error message is “The current user’s role must have user editing capabilities.” even though a site administrator does have the ability to edit users

Please let me know what permissions are needed for a user to create or edit products and services.

Thanks
