Here is the problem. I go to a custom module created by sugarcrm via studio and it has 150 results with showing 20 per page. When I click the button to show the next page it just reloads the current page. No PHP errors, no JS errors, nothing in the debug log.

Current set up is

CentOS (kernel 2.6.18-128.el5PAE)
SugarCRM 5.5.2
Apache/2.2.15
MySQL 5.1.49 (Perconna's fork I believe)
