I incorporated the USA Extremes and State Extremes into my menubar some time ago. This evening I tried to load my web site and discovered it was unreachable. After fiddling around looking for problems there I tried to load my self-hosted testing site with the same results.
GoDaddy tech support confirmed that their hosting was performing normally, and since both of my identical sites were down I assumed it was a problem with my site. The error logs on my GoDaddy site pointed to menubar.php as the culprit. When I tried to load my site on this computer's WAMPserver, it stopped loading after errors related to usaextremes.php and stateextremes.php, which gave me the source of my problem.
I removed the Extremes code from my menubar and everything loaded normally once again. I liked them, and I'm not sure why these scripts suddenly failed.
EDIT: It seems that the CPC is currently down. Once it's back up these scripts may function correctly again!
