Hey guys,
I use a customised version of the JA Purity template for my site and I noticed it doesn't display correctly in IE8 unless you run the browser in compatibility mode.
Anyway if you add the following straight after the <head> tag in your index.php file it will automatically force IE8 into compatibility mode for everyone who views your site (many of whom may not be bothered to manually switch compatibility mode on):
<meta http-equiv="X-UA-Compatible" content="IE=7" /> <!-- for IE8 Compatibility -->
I'm pretty sure that many of the IE8 JA Purity display issues stem from the gte IE 7.0 conditional statements, so if you manually change them to if IE 7.0 it may work too.
Regards
Julian
