Well, it seems adding this to the root file causes the problems viewing in IE:

AddHandler application/x-httpd-php5 .php

Removing that line means I can view the forum without problems in IE, but then stops WP admin from working properly (why I added it in the first place).

Any way of stopping a child dir (the forum dir) from inheriting that rule from the parent dir, or should I just add the line to the WP admin dir .htaccess file?
