This is the issue:
When I click the second tab 2 (or tab 3) all the text moves up and
hiding breadcrumbs
This is how it looks to the first time (all ok):

As it appears after pressing the tab 2 (all the text moves up):
http://www.veggiefriends.it/component/c ... .html#tab2
I attach a screenshot:
This is the answer of the support JReviews:
Something on your site is conflicting with jQuery UI tabs, most likely some script in your Joomla template.
Notice that when you click on a second tab that the #tab2 is appended to the url. That should not happen, check how it works on the demo site:

(the url never changes when you click on tabs).
I see some "SmoothScrolling" script loaded by your Joomla template, it is possible that this script is causing problems.
