Multiple language problem after login

[febern]

Well, i've translated all most important things for my users into my mother language (hungarian). When they are filling registration fields it's hungarian, BUT after they click on login, its change to English language <img> And i can't figure out why happen this if the registration is hungarian and if a hungarian guest visit my site, it's hungarian language as well, but after he logged in, it's changed to English.

Please help me. Thank you!
