wp-admin not working

I just tried to switched from mqTranslate to qTranslate X. Everything went okay, until I tried to login to the back-end.

– My WordPress default language and q-translate default are the same
– Detect the language of the browser and redirect accordingly results both checked and unchecked in this problem.
– The WordPress Address (URL) and Site Address (URL) are different on my site. I have installed the site in a submap.

I tried some tips mentioned somewhere else on this site, but no solution.

http://www.url.com/submap/wp-login.php does work apparently.

Only disabling this plug-in and activating the old one solves the issue completely.
