I recently tested a new template for a site (University by Shape5). I tried to get a quick preview before setting the template as default by adding
?template=university to the url. But the template was not rendered correctly (no main menu, text-width 100%, no footer etc.). It was not until I assigned the template as default that it was rendered propperly.
So my question is: Is there any difference between how Joomla renders a template when using
?template=myTemplate, as opposed to assigning the template to a menu item (or as default template)?
