 * Hi,
 * I can’t seem to log in to my dashboard anymore. After I tried to change some 
   code in my childtheme I got an error. Fixed that via FTP Filezilla. I was able
   to log in, but as soon as I tried to change same very basic settings (not in 
   css), I got this error:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /var/www/vhosts/heidepost.nl/subdomains/test/httpdocs/wp-content/themes/childspacious/
   functions.php:1) in /var/www/vhosts/heidepost.nl/subdomains/test/httpdocs/wp-
   includes/pluggable.php on line 1196
 * I also got a Maintanence Mode error, but I removed the plugin via FTP.
 * I already tried to fix functions.php from the childtheme, as well as pluggable.
   php. But so far it hasn’t resolved anything.
 * Can you help me?
