I have a conflict between my theme and this plugin (used process of elimination). Only on pages where I'm showing a portfolio, it throws this error: Call to a member function get() on a non-object in .../wp-includes/query.php on line 27.
There is a bug ticket at wordpress about this error (http://core.trac.wordpress.org/ticket/15881):
There are timing issues in WP where some code in plugins, specifically wp super cache, make called to wp_cache_get before $wp_object_cache is initiated.
Any help would be greatly appreciated. I'd hate to switch to a different event manager over this (cause I can't switch themes!)
