Hi,
If you are a developer or designer of Joomla 1.5 and have recently moved to Joomla 1.6, 1.7 or Joomla 2.5 you will see that setting the parameter of tp=1 in url doesn't show you module positions anymore. So if you are wondering how to view module positions in Joomla 2.5 its simple, you go to Extensions->Template Manager, click on options and set 'Preview module positions' from disabled to enabled and the old tp=1 will start working.
