If viewing through Firefox, you see the up-to-date site (current posts, layout, etc).

If viewing through IE, you don't see anything more recent than March 19th (posts, layout, etc).
*edited to add: the same problem happens in Google Chrome too.

If I go into my dashboard in IE and then view the site, I see everything (except for my GFC and Networked Blog widgets) current.

But, if I update in Firefox (my preference) it doesn't update IE.

HOW do I fix this?

what version of Atahualpa and WP?
All I see in both Safari and IE and Firefox is the 3.19th post

try disabling all your plugins and see what happens

I see everything up to the 30th in FF IE8 Opera, Chrome and Safari. The biggest issue I have is the large file sizes of the images makes the site load slow.

well this morning I also see the 30th, but in IE, I don't see any images.
there is an error showing up in IE on line 42 of the generated source
