Hi there!

My configuration: joomla 2.5.3 with installed slovak language and k2 2.5.5 ... i've installed slovak language for k2 and it does not show... any ideas why? Thank you

Not sure I can help here, but I've think you have to have the same language installed in Joomla before it works.
Think I read it in some forum.

thank you for your answer, but that is why I wrote "with instaled slovak language" (the joomla translation was instaled and set to default before K2 installation .. other translatitions are working.
