Figured it out…. one of the scripts that came with my WP theme had gotten corrupted somehow. I uploaded a fresh copy of the corrupt script, and everything works now. Weird.
Thank you for your reply. I’m using the plug-in “Flickr Gallery” to display thumbnails of my Flickr stream in my theme’s footer. I am not familiar with code… I just installed the plug-in and followed the directions. Everything works fine, except on the home page.
My site is here.
