[SOLVED] After upgrade, header and menu missing on only some pages, only on Firefox
 

I just upgraded a client's site to Atahualpa 3.7.13 and have a peculiar problem that seems to happen only with Firefox. The problem: the header and menu show everywhere EXCEPT on 3 pages: Home, Policies & Fees, Awards & Achievements (sidebar button). This doesn't happen on Chrome, Opera, IE, or Safari; only Firefox.

I know all about the header image issues and created a static folder for it (all with proper permissions); have had no problems with upgrades til today. I looked throughout the forum and have clicked "Save" on the recommended screens. Here's the site: http://www.SoCalPianoAcademy.com. Since you can't see the menu on that Home page, you can begin clicking around by hitting the sidebar "Sign Up for Our Newsletter" button; you'll see the header and menu on that page.

Any ideas??

Although I had worked on the problem for an hour or so, suddenly the header & menu have appeared on the 3 pages from which they were missing. I always clear the cache when making changes, so I don't think that was it. Mysterious. As in all web things, I am learning to wait a bit before panic sets in. (!)

You have a caching plugin so you see the cached page till it changes or the cache timer pops.
