Fatal error: Cannot redeclare class Services_JSON in ........administrator/components/com_k2/lib/JSON.php on line 128

I get this fatal error anytime it try to publish an item to a category both when saving the article in the admin and when I click on the menu item in the front end.

Any thoughts?

Thanks for the response - I am using the most recent update; the one released July 1st. Is there something I'm missing?

Scratch that - I realized that I did not install the most recent update....it works fine now!

Thanks!
