Hi @jamesgwhite,
Its happen when you are logging with a customer privileged user credentials,
or I can say a user who has been registered as a customer to your site.
If there is any other co-admin account, you can request them to grant admin role to you.
Else then you can try with FTP access of your site and create a new admin user account as described
here https://www.wpbeginner.com/wp-tutorials/how-to-add-an-admin-user-in-wordpress-using-ftp/.
Also if you have any specific plugin that manages the user roles, you can disable those through FTP/ File Manager by renaming it.
And try to login in again.
If this doesn’t resolve it, please provide login credentials for your site in a secure note, including:
– Link to your site
– WordPress Admin username / password
– FTP/CPanel Credentials
To create a secure note, click the key icon underneath any of your posts.
Hope it helps
Thanks
