calendar menu item wont show template modules

im new to joomla and it looks like an airplane control pannel.
calendar menu item (and others event booking menu items) wont show template modules and wont show anything except actual content of plugin
this is a bizarre conflict with site's template (i think) and only working page is categories list. why?

plugins are published.
tried almost everything, tried to add modules and also wont work (wont show on screen).
what am i doing wrong? can you help?

Hi Daniel

From what I see, it seems there is something conflict here. Could you please submit a support ticket sending us super admin and FTP account of your site so that I can check to see what's wrong and get it corrected for you ?
