when you access orca from admin, you will see on the right side of the page "en" this is the link to the language compiler, click on that, and in most cases 75% or so (bad statistics) it will say language compiled sucessfully. now if you have tinkered with anything, trying to get that to go away, then it may not compile the language. let me know if this works out for you. i have done this on three different installs, it took me about three weeks to figure out it was half my problem as i see more ignored some errors on the install.
