When i edit language variables (via ftp or admincp doesnt matter), there are no changes in my board. Also language files are writable. (777) How can i solve this problem? Thank in advance for your help
Are you having only the default english language or any other language files?
Also make sure you edit them correctly.
My problem is solved. I tried to edit some phrases in online.lang.php, but i guess that those phrases moved to index.lang.php in MyBB 1.6.3. Sorry for my bad english
No problems. Glad your problem is solved.
