I have been working on building a new site with Concrete5 and I love it. Until now I haven't had any problems. I downloaded DynamicIFrame and was trying to add a block and now I can't access my website at all and all I am getting is this error:

Fatal error: View::render() [<a href='view.render'>view.render</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition &quot;DynamicIframeBlockController&quot; of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /home/spreston/journeytojoy.org/concrete/libraries/view.php on line 734

If anyone has ever had this and knows how to fix it I would appreciate any help. Thank you very much!
