500 internal server error after update

[ggaryg]

I've been running my website for years and now yesterday I update 2 files, the same way I always do, and when I try to load them in a browser I get

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

The log says this:

[my ip] - - [17/Jan/2015:00:07:55 -0500] "GET /site/index.php HTTP/1.1" 404 - "-" [my agent string]

Permissions are 644, same as for the other files. I haven't encountered anything like this before and am totally stumped. Can anyone help?

Usually found in the document root folder named error_log.
