This is something I just found out and it is very peculiar. There is no problem whatsoever in FireFox.
I don't know the results in IE6, but what I found out is the following.
When I'm logged into my blog, the front page (standard 10 latest post) is visible in IE7. When I'm not logged in it doesn't show any content at all.
I have another site also running with WP 2.1.2 and there the problem does not exist. The only change known to me is the theme. On the other site, I use a translated version of the Kubrik theme.
Has anyone experienced the same problem on their blog already? Any tips would be very welcome.
