I’m having the same problem but I don’t know how to “remove any white spaces …” How do I get that done?
My error says:
Warning: Cannot modify header information – headers already sent by (output started at /nfs/c04/h01/mnt/59212/domains/preparetogrow.com/html/wp-config.php:47) in /nfs/c04/h01/mnt/59212/domains/preparetogrow.com/html/wp-login.php on line 12
