WordPress Won't Log in, no error Message

Hello,

I have one of my clients’ sites running WordPress 3.4.1 and recently migrated it from my development server to his server. Upon doing so I began to have issues with logging in.

I can get to the log in screen and the front end is perfect. When I go to log in I’m redirected back to the log in page without any error messages.

If, while at this point, type http://www.competitivetelecoms.com/wp-admin into the adress bar, navigate to the page (which is of course the page I’m already on) and attempt to log-in I can; doesn’t work if I just do a normal page refresh.

I’ve gone through the steps at http://codex.ww.wp.xz.cn/Login_Trouble, I’ve cleared my cache and cookies, tried on Chrome, Firefox, and Safari with the same results, tried a different template, and tried deactivating my plugins.

I’ve tried searching for an answer but everyone just keeps saying “delete your cookies” or “deactivate your plugins”, which doesn’t do me any good.

Any one ever have a similar issue?
