Zend Framework _Redirect() not working but header(location:) is working

I just got a new server and zend framework seems to be working properly EXCEPT, when a member posts something , they get a white page because $this->_redirect('/somepage'); doesn't work...

Am I unaware of some php setting or vhost setting I'm supposed to have? Header("Location:/somepage") works just fine.. :\

I've been looking through my logs with no luck. Also, my images aren't 开发者_JS百科getting uploaded even when folders are set to 777...

I'm stumped. Let me know anything you need to help me fix this. It's a large site that is about to dissolve if this issue stays for longer than a couple days..

Some thoughts:

• Xdebug installed? Sometimes Problems with crazy errors
• Check Autoloader, possible redirect helper not found?
• Check Zend Framework (all files available?)

Have a look into your php.log if exceptions are thrown.
