 * I’ve read a couple of related posts but I’m having a partly different issue with
   my installation, as I cannot access my backend either any more. When I attempt
   to load my page, the page loads with these messages at the top:
 * Warning: session_start(): Cannot send session cookie – headers already sent by(

   augustinianum_2013/wp-content/themes/cleanspace/functions.php on line 806
 * When I try to login, I receive these error messages and cannot login. For me-
   obviously- there’s something wron with a plugin or the theme, however I did not
   make any changes. But as I can’t access my backend, I’m completely lost now…

 * Thank you for all help in advance!
    Best regards Andreas

 * Access the site using your web host’s FTP or file manager, and rename the faulty
   theme so WordPress cannot use it. Ensure there’s a default theme installed, and
   WordPress will use that.
