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:
