Password protected pages redirect

I’ve been running a small fashion site (oneof.dk) , and suddenly some of the password protected pages were visable. Nothing had changed, neither wordpress or any plugins.

I’ve tried updating wordpress and disabled all plugins, and this at least helped by not making the pages visable. Now however I just get a redirect to the same login page every time i’ve submitted the password.. (http://oneof.dk/wordpress/logint/)

“logint” is password protected as well as the subpages here.

‘WordPress address (URL)’ and ‘Site address (URL)’ are the same, as i’ve seen this has been a problem on other sites. Password protection is done through wp-admin (no plugins).

I can track that I submit to the postpass page but I get no return.

Hoping someone could help 🙂
