 * Hi!
 * I’ve just tried installing v2.2. The database is all up and properly connected
   to the script. That is I have modified the wp-config.php file and I’ve run the
   intall.php. All is set up now but for one thing, I keep getting this error message
   when logging in:
 * Warning: Cannot modify header information – headers already sent by (output started
   at wp-config.php:25) in wp-admin/install.php on line 15
 * There are more error messages like that depending on what page I am trying to
   open.
 * Hope to get help soon as I am excited trying the blog.
 * With cheers,
    Hanns.

 * When you edited the wp-config.php file, you left blank lines or spaces at the
   bottom of the file.
 * You cannot do that.
 * Edit the wp-config.php file and remove all white space at the bottom of the file.
   The very last text in the file *must* be the “?>” characters. No spaces, no tabs,
   no empty lines.

 * Oh…I did not realize it was significant. I just deleted 3 spaces after the “?
   >” and it worked!!!
 * I have another script that has the same problem…now I know how to solve it.
 * Thank you for the very very quick reply. Appreciate it a lot!
