Can’t Log In After Initial Installation

Have a look at your wp-config.php and make sure there are no letters (even spaces) before the <?php or after the ?>

Checked that…no spaces or letters.

The trouble started when executing install.php

Warning: Cannot modify header information – headers already sent by (output started at /home/greaycom/public_html/blog/wp-config.php:1) in /home/greaycom/public_html/blog/wp-admin/install.php on line 16

The following message means that php can’t change the header (which the code in line 9 in wp-login.php is trying) because wp-config has already send one or more letters.
There is no echo in wp-config, so in this case there are letters outside of the php-code like spaces or linefeeds. Check again.

I figured it out. Don’t use FrontPage or Expression to edit the wp-config.php file. Even though it appears nothing is in front of <?php or after the ?>, for some reason these two programs insert wierd characters. I used Adobe GoLive to edit.

for future reference, thats a plain old textfile, use notepad

loading golive to edit it is a good deal of overkill.
