There is a bug in the FAQ:

"What if I make a mistake in my post?"

The answer to the question "How do I log in" is displayed

Problem is in faq.inc.php on line 26:

PHP Code
$ubbt_lang['B_MISTAKE'] = $html->substitute($ubbt_lang['B_HELP'], array("MAX_EDIT_TIME" => $config['MAX_EDIT_TIME']));

Same Problem exists for "How do I change the number of posts displayed on a page?" > on line 27:

PHP Code
$ubbt_lang['B_MOREPOSTS'] = $html->substitute($ubbt_lang['B_HELP'], array("TOPICS_PER_PAGE" => $config['TOPICS_PER_PAGE']));
