ie8render7 / x-ua-compatible header in functions.php

The users of my site started complaining that a text box shrinks whn you type text in it.

It turns out that functions.php was setting the x-ua-compatible header to IE version 7. This caused the display problems.

The code:

PHP Code:


		
			
    // IE8 emulate IE7 mode

    if ($vbulletin->options['ie8render7'])

    {

        @header('X-UA-Compatible: 7');

    }

It's supposed to only affect IE8, but it did not.
Where is that 'ie8render7' being set in the options?

I suppose the Internet Explorer detection mechanism used by the older versions of Vbulletin is no longer working. :erm:

It's under "Cookies and HTTP Header Options" and it's called "Send Internet Explorer 7 Compatibility Header". FWIW, it's been removed in vb4 (at least it has in 4.2.2, it could have been in an earlier version).
