Cannot launch the site

I created a web site in https://www.apeb.pt/2016/.
Today I tryed to reconfigure to https://www.apeb.pt.
Now I cannot launch the site neither in https://www.apeb.pt/2016 or in https://www.apeb.pt.
I get this message:

Warning: require_once(/home/ape10001/public_html/2016/admin.php) [function.require-once]: failed to open stream: No such file or directory in /home/ape10001/public_html/2016/index.php on line 10

Fatal error: require_once() [function.require]: Failed opening required ‘/home/ape10001/public_html/2016/admin.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/ape10001/public_html/2016/index.php on line 10

Can anyone help me?
