Are you saying you don’t see the sidebar on the home page of the site?
I’ve opened this site up on three different computers in two different locations and all of them show me the sidebar on the home page. When I log into the site and look at the home page, the sidebar is gone (as it should be).
This doesn’t seem to be a caching issue. There is no caching plugin on the site and the two computers in different locations had never seen that site before, so the cache was fresh.
