I really, really hate this. If you view the site in IE7 it looks retarded because everything is centered. It looks fine in Firefox of course. Is the problem IE 7 or the CSS? I'm using phpkaox. I believe someone gave me a mod for my CSS because when I upgraded to 2.18 all of my blocks turned into big chunks of text with no breaks. The mod was the only way to get my blocks back to normal.

I upgraded to 2.3 Final yesterday.
Now I have a symbol in the front of all of my block titles. In Firefox it is a Diamond with a Question mark. In IE 7 it's a square.

phpkaox is really an old an not compliant theme..
anyway if you open the theme.html file you'll see plenty of tag with the align="center" attribute.. so it should be enough to remove this attribute from the parent td of the center blocks..

concerning the strange symbol it's probably caused by an unparsed character you have before block titles.. did you hack this part? remember that 2.3 change the charset to utf-8.. so there's a chance to have non recognized character..
