You've got something else going on in your system with other plugins or something. You'll have to track that does first.  Try disabling other plugins.

It sounds like it is being called but $query contains nothing it seems.  Try this to see if "We're Here" shows up.

add_filter( 'parse_query', 'my_parse_query' );
function my_parse_query( $query ) {
     echo "We're Here!";
     print_r( $query ); die();

Want to figure it out without having to "mentally execute" the code?  Get an IDE w/debugger (I use PhpStorm+XDEBUG.)
