The Orca Forum Shows wired cripled text

The Forum shows unwanted text there. 

i logged in as an administrator, clicked on modules, click on Orca Forum, and then clicked on Compile. It gave me a success message, but it did not show the right text. i still see things like : [L[Forums Index]],

There's no need to post in two topics for one question. Once you compile the languages, the confirmation message will show uncompiled text. For the changes to truly take effect, you must refresh the web page.
