Thread: After users login, the site takes them back to home page as if nothing happened.

After users login, the site takes them back to home page as if nothing happened.

When users try to login, the site accepts the details, even if details are correct, it takes them back to home page as if nothing happened. No login/no dashboard/edit ads.
It stills shows the register/login links at the menu bar. I mean, there is some problem and the site doesnt redirect user after logging in , instead it takes to the home page. All was working fine, though i had made some changes in WP supercache plugin, but that was a day earlier to this problem. And was working fine..till 10-12hours after making the change...please help!
