Installed, enabled and now my whole site goes blank until I disable the module.

My server side has all the proper PHP modules enabled as required for Simple RSS

Any idea whats causing this?

My site is: mindgame-productions.com

The menu item that goes to Simple RSS is "MGP News Feed"

Now when you click its showing error:

Fatal error: Cannot redeclare class SimplePie in /nfs/c07/h03/mnt/114616/domains/mindgame-productions.com/html/libraries/simplepie/simplepie.php on line 396

A search for "Fatal error: Cannot redeclare class SimplePie in"
