I’m receiving the same error, and I made my edits using Dreamweaver. Are there any other suggests as to what the problem could be?
My full error reads:
rr
Warning: Cannot modify header information – headers already sent by (output started at /home/xxxxx/public_html/mk/wp-config.php:1) in /home/xxxxx/public_html/mk/wp-includes/functions.php on line 1348
And if I try to ignore the error and continue with the installation, eventually, I’ll get a page full of errors and the login will not work.
