Users can't access 'My Dashboard'
When clicking 'My Dashboard' users are asked to log in again and then get "Access Denied. Your site administrator has blocked your access to the WordPress back-office."
This also happens from the /login link they get on their registration email.
Have searched and read other posts around this topic - have deactivated most of my plug-ins and permalinks are set to 'post name'
Hovering over the 'My Dashboard' button shows the my domain/dashboard link but on clicking it redirects to something else!
Directly inputting mydomain/dashboard does bring up their dashboard.
