In Forum.php, I edited the Topics function to display 70 topics at once.
function Topics() {
if(isset($_GET['start']) && is_numeric($_GET['start'])) $limit = Convert::raw2sql($_GET['start']) . ", 70";
else $limit = 70;
The problem is, the pagination links at the bottom go in increments of 10!
When you click on the link for Page 2, it puts &start=10 in the URL instead of &start=70 and it shows way too many pagination links!
