[support] Panels as taken over

Hi, Drupal 7.15 with Ctools, panels, pages, views installed and enabled. My site is dev.apacecouriers.com I am learning panels and was working on site template and now I have a page displaying my panels page but the problem is I can not access any other content. I can log in and out but no matter what I try to open - content, panels, structure ...any thing in the menu..It displays the 'homepage' (the site template) I have uploaded the default 'panels-pane.tpl.php' file and when that didn't work I stopped messing about and came here for guidance. Can anyone point me in the right direction? Help? Howard
