I'm getting this message when I try to change the normal display or the floating display:
Fatal error: dd_page_for_normal_display() [function.dd-page-for-normal-display]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "DD_Sphinn" 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/daveicom/public_html/wp-content/plugins/digg-digg/include/template/dd-template-normal-display.php on line 63
I have no idea why it happened or what to do about it. I have deleted the plugin and reinstalled. I also upgraded to the latest version. That's the extent of what I know about fixing it.
