When I click the "Save changes" button at the bottom of this page, the browser (I have tried IE, Firefox, Safari, and Chrome) spins, and spins, and spins. Eventually I get an error that varies by browser. This is the URL it is trying to load:
"http://www.<my domain>.com/wp-admin/themes.php?page=functions.php"
In the case of Firefox, I get a "Problem loading page" error. Basically, it times out.
BTW - I am on WP 2.7
