Hi there...If I leave the breadcrumbs on (that's the idea) I get this message in the browser... "Fatal error: Cannot redeclare class Calendar in /home/mbsinc/public_html/current/modules/mod_k2_tools/includes/calendarClass.php on line 33" ...whenever I try to call RegPro component in the frontend.I found that in calendarClass.php, you have a class called "Calendar", and it seems to me that Joomla Showroom is using the same class name for their component, so it cannot be redeclared. All I did is to check if the class already exists before declaring it ( if(!class_exists('Calendar')) { ) ... Now, if  you are using exactly the same class as, I guess I'm OK, but otherwise someone needs to change the name of his class to avoid conflicts...ThanksClaudio
