I am trying to change the generic permalinks on my webpage and it causes some problems.
I am getting this error whenever I am trying to open the pages:
The requested URL /wanted-good-phd-students-in-petroleum-management was not found on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
Since this happened I changed back to the default numeric permalinks but two of the links just won't change even though I have been going in to the pages to check the permalink and then checking the link in the menu.
As you can see two links doesn't work on my page:
Research>Good Phd Students Wanted
Teaching> University courses
Does anyone know how I can change this?
