Edit Profile and Login links not linking to correct page
I've activated an old website with the Vantage theme (version 1.4) and removed the old pages and any duplicates that occurred when I imported content from another Vantage website, but some page links are not working - like "Edit Profile", "Login" etc. Pages either come up blank, display a "Leave a reply" template or say "Page not found" (very strange). I am also trying different permalinks but no luck.
Has anyone had any experience with this or know how to get the login and edit profile pages to work?
I also do not have any page templates under the attributes section to link the categories and event categories (posted in another thread). Any advice would be appreciated - I'm scratching my head over this one and have tried all sorts of variations to make it work to no avail.
