Zend Optimizer is a server setting dealing with PHP. They must have made a change to the server and not realized that they broke the site . I am also getting a bunch of JavaScript errors on the front page.
I don't think it is broken, but as Brandon mentions the Zend optimizer is required to use the site. IT is CRAP if you ask me.. I looked into downloading the zend and it wanted a login and that is a bit far to open a website.. anyone know how to get intouch with wakesiderides to protest?>
