The Events Calendar is giving me an error message on the calendar page
 

Just recently this error message appears when the "View all events" link is clicked on my home page. I've been using this plugin successfully for months, this is a new problem. What do I need to do to fix this?
I'm running Atahaulpa 3.4.9 on Wordpress 3.1 . The plugin is The Events Calendar by Shane & Peter.

I experienced so many issues with The Events Calendar ....that I changed to Joe Dolson's My Calendar http://wordpress.org/extend/plugins/my-calendar/ and honestly, it really is simply the best!

Can someone take a look at these links and give me a fix. My host recently moved all the files and I'm thinking something was goofed up in the move.

Have you checked with the plugin author?

if you switch to twenty-ten and have the same issue then it's not theme related.
