Recent Posts Show up In FF but Not IE… I'm Stuck Please Help!!!

Hi all, I have a blog I post to daily and since Nov 27th my new posts are not showing up in IE or Chrome but they show up fine in FF.

If you go into the category where my posts are in IE you can see the new posts there but not from the homepage.

I have been posting to this blog well over a year with no issues.

I suspect it may be something to do with the header menu as I have discovered a problem with it at the same time.

I had a custom menu set up and in my troubleshooting I changed the theme back to the default menu but in all browsers it still shows my custom menu but only on the homepage… once you go to any other page the current menu loaded shows properly.

I tried deleting the custom menu and it still shows that menu from the homepage on all browsers…

My site is at http://bestpanicattackcure.com/blog

Thanks so much for all your help

Mark
