There's a typo in the new language -
temp/mess_reply.php
$ubbt_lang['TOO_LONG'] = "This private topic has reached it's maximum length of %%TOTAL%% replies.
You cannot add any more replies to this private topic at your current member level.";
That should be "its maximum length". His Hers Its.
Only ever use it's if you could use "it is" in that same spot
