Front end event listing Joomla 1.6

Tested on the sandbox:

1. Event listing
The events do not show up front end: I created a menu to events listing which produces a blank page.
The link generated is this:
index.php?option=com_civicrm&view=Events&layout=eventlisting

However, this html link shows the events correctly:
index.php?option=com_civicrm&task=civicrm/event/ical&reset=1&page=1&html=1

3. Single event registering
If you go through the menu to create a single event listing, the event will show up, but the registration button is not working. If you go through the modified url for event listing which I created on the sandbox site, the registration button is working fine.
