Still similar problems. It appears to work at first, though the instructions text is not visible using my dark style. I assume this is because you are hard coding the text color. Inputting a URL results in:

Forbidden

You don't have permission to access /youtube.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Changing the youtube.php permissions to 777 (is that safe?) denies access to the main input page:

Internal Server Error

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

Please contact the server administrator, xxxxxx@xxxxxx and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.
