Missing Control Panel

I see 500 error so its hosting related, im gona ignore this for now since your host said its a hacker attack.

Email your host to restore the website from their backups, choose a backup that is one or two days old.

Once the website is restored and working, do the following:

* Update WordPress.
* Update all plugins.
* Change your cPanel password.
* Change your WordPress admin area password.
* Change the password for all MySQL users.

Then post here so we can take a look and do more security improvements.

Your website is returning a 500 status code, which means that you have a PHP error preventing your website from appearing.

Try adding this to the bottom of your wp-config.php file and then reloading the page:

error_reporting( E_ALL );
ini_set('display_errors', 1);

The PHP error(s) that are causing this problem should then appear.

His website was hacked, php errors are the least of his worries now.

He must restore the website from a clean backup and follow the instructions I gave him above.

There is no proof that his website was hacked. Until you see what the errors are, you’re shooting in the dark. It’s just as possible an automatic update caused one of his plugins or themes to error out.

Maybe im taking his web host words too seriosly. Could be a hacked website or a simple auto update conflict.

Thanks to you all, I will contact my host shortly and then let you know what they said. Hopefully it will sort out fine.
