Updated IP address causing sites to malfunction

Hi All

I've got a real issue now with my sites - strangely coinciding with this change that was made.

The symptom is that left and right sidebars disappear on all pages or all pages other than the home page. Obviously, this makes for less complete pages.

Could you look at this ASAP? It may or may not be my subdomain setup, but I do not know.

Thanks,

JeffL
