Going On Vacation-404′s

I’ll be away from the 22 cnd of Sept. until Oct. 6th.

My website is messed up.
If you click on a link in my menu for a page chances are 50/50 you will get a Page Not Found Message.Even typing http://mccormicky.com into the address bar triggers a 404,sometimes.

If you refresh the page once or twice the page will load.But this is not how a website is supposed to work.

I’m very confused by this recent development – thankfully it is only happening on my domain and not on any of my client or friend’s websites.

I’ve checked the .htaccess.I’ve changed permalinks.I’ve checked the code in myheader. I have no idea.I am totally stumped.
Everything seems to be back to normal.Crosses Fingers.
