Hello, I am running a moodle 2.0.2 version, and I am unable to change language pack. Whenever I try to install it, I just get a blank screen on the path "admin/langimport.php?mode=2" and when I go back and refresh nothing happens. I also tried using manual install and nothing happens. I made sure I used a portuguese 2.0 pack, got it to /lang folder and unziped it. It is also to the 0755 permission, like all the other files there, so that should be good.
Whenever I got to language packs I only have English(en) on the left side, and updating does nothing (says they are already up to date).
Please help me out. Thank you.
