You rockettheme template uses a template override which will not show any mainBody element for URL's with 'frontpage' in it.
At first, it is meant to only block com_content from appearing at frontpage, but also at the same time clashes with other component that has 'frontpage' in its URL.
Please consult with Rockettheme to ensure that only 'com_content's' frontpage is blocked instead of any url with 'frontpage'.
As mentioned by mark, this works well
tisklife.com/index.php?option=com_community
but not this link:
tisklife.com/index.php?option=co
... &Itemid=49 <-- with a frontpage phrase in it.
