# Error 500

 * I have recently updated my wordpress site to the latest version of wordpress.
   
   Now, both the website itself (www.sonitron.com.au) and the admin login page (
   www.sonitron.com.au/wp-login.php) show an error 500. Is there any way that I 
   can access the site and undo the update to get the site running again? Thanks

 * Hi,
 * You need to contact your web hosting company.
    Ask them to take a look at your
   error log to find out what is causing this issue.
 * If it’s a theme or plugin. You can use FTP to access your server to remove it.
   Or ask your web hosting to help remove it.
 * If it’s WordPress, you will need to re-install WordPress via FTP.

 * Ask your web hosting company for help, if you do not know how to use FTP.
 * Thank you

 * I have deleted all plugins and the theme, and have re-installed the previous 
   version of wordpress (4.5.2) and I am still getting the error message.
    Any suggestions?
   Thanks

 * If you do not have access to your error logs, Denzel is correct, try and get 
   a hold of your hosting company who can look at your error logs for you.
