Some additional info -
Looking around in vbbridge.php, near the top I see:
PHP Code:
if (basename($_SERVER['SCRIPT_NAME']) == 'upload.php') { return; }
and
PHP Code:
if (basename($_SERVER['SCRIPT_NAME']) == 'media-upload.php') { return; }
which looks like its bailing out of the script if either of these two .php files is being parsed. I commented them both out and was able to get into the media gallery, but uploading an image from a post had bizzare results - a warning popped - clicking OK, go ahead - a new Wordpress dashboard was placed inside of where I normally choose the image to upload.
