Hello,
I went to http://www.pappystexasbarbeque.co.uk/events/ and it seems the Tribe events calendar is working fine there – if you want a different view to display than the current view (which is the Photo view), you should able to adjust this by heading to Events > Settings in your admin and changing the “default view” option to something like “Month”, “Week”, etc.
As for the widget – where specifically are you trying to add the widget? Can you link to the page on your site whose sidebar you’re trying to populate with this widget?
Thank you!
George
