It is usually caused by a filter or an action not properly declared. Somewhere in your theme or plugins is a line like:

add_filter( 'hook_name' , array( 'wphpc_PAnD', 'someMethod' ) );
// or
add_action( 'hook_name' , array( 'wphpc_PAnD', 'methodName' ) );

which register class method with hook for a action or filter, but this class (wphpc_PAnD) does not exist.
Check if file with class definition is included and there is no typo in the class name in add_action() / add_filter().
