It recognizes logged in users fine. It's when you view the page when you're not logged in. The script doesn't even get all the way through global.php before it starts spitting out information...

That link you posted works fine for me. Shows the link back to the page, and "not logged in".

Really?

This is what I get when navigating to that page while not logged in:

Code:

Notice: Undefined index: HTTP_REFERER in /var/www/vhosts/myspacepros.com/httpdocs/forum/includes/class_core.php on line 1574



Unable to add cookies, header already sent.

File: /var/www/vhosts/myspacepros.com/httpdocs/forum/includes/class_core.php

Line: 1574

I'm a bit lost now....

That's because you have error reporting set to include notices in PHP. Which generates a 'notice' output if $_SERVER['HTTP_REFERER'] isn't set when vB tries to do this:

PHP Code:


		
			
        define('REFERRER',       $_SERVER['HTTP_REFERER']);

When I hit the page, I'm clicking the link on this page first, so the HTTP_REFERER is set with the vborg page I'm being referred by. If you hit your page without being 'referred' by another page (i.e. type the URL in by hand in your browser), then HTTP_REFERER won't be set. And because the notice is being printed before vB sends the page headers, it screws up page output.

To fix that you'll need to turn off 'notice' level reporting in php.ini:

Code:

;   - Show all errors except for notices and coding standards warnings

;

error_reporting  =  E_ALL & ~E_NOTICE

Of course the real fix would be for vB to test for the existence of $_SERVER['HTTP_REFERER'] before using it in a define(), so if you want to go submit a bug report on vb.com ...

Thank you very much cheesegrits. I'm a little embarrassed I didn't think of that myself to be honest. Thank you.
