Can anyone help me? I updated my site and when I click the tabs of my first two pages (which I made before my last 10) I lose the tabs for my last 10 pages. Can someone try and see if it happens to them. Click on Ozzie Smith or Bart Starr and the othe tabs vanish...

No, nothing vanishes at all.

You are probably seeing those first two (old) pages from your browser's cache. Clear the cache and try again.

If you're using IE, it's Tools, Internet Options, Delete Files, click OK.
