Updating profile in Vantage gives 404
When Vantage theme is activated I cannot update my user profile and get a 404 response. Also if I log out of wordpress while Vantage theme is activated I am unable to log back in. All attempts at getting to the dashboard redirect me to 404. I have to delete the theme from the files by ftp and then log back in.
If I enter wp
-login.php it redirects to /login which is a 404
If I go back on my browser so the admin page appears (but im not logged in) if I get redrected to /dashboard/ and this is a 404 page too.
Am I missing something with permalinks? It is all fine when I have twentytwelve or any other theme activated.
