 * Check your wp-config.php file – most likely there is an empty line or a blank
   space on the top before the
    `<?php ...` bit. Reading: [FAQ in the Codex](http://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F)

 * Well, i am so stupid, and i don’t know now what i have to do. But, there is a
   other error warning too on login page:
 * “
    Warning: Cannot modify header information – headers already sent by (output
   started at /home/vmfptdug/public_html/datanord/wp-config.php:1) in /home/vmfptdug/
   public_html/datanord/wp-login.php on line 9 “
 * and on install page was one error too :
 * ” Warning: Cannot modify header information – headers already sent by (output
   started at /home/vmfptdug/public_html/datanord/wp-config.php:1) in /home/vmfptdug/
   public_html/datanord/wp-admin/install.php on line 16 ”

 * I don’t think you managed to read the material we linked to in this short time(
   it’s a long page!).
    So, unless there is something new, please, read it carefully,
   do what it says. All your problems come from the same place: line 1 on wp-config.
   php file.

 * I have a unique problem. I was messing around with MySQL and decided to try changing
   my admin login password using MySQL. Here is the query I used.
    UPDATE wp_users
   SET user_pass = PASSWORD(‘mypass’) WHERE ID = 1;
 * It worked beautifully. Only problem is, that I cannot login now. I am using wordpress
   on the standard apache 2, php5, MySQL 5 set up. Anybody have any ideas on how
   to get around this? (BTW the PASSWORD(‘mypass’) part allows the password to be
   hashed.) I have tried changing the password to not hash but this doesnt work 
   either. I also have the mail settings turned off, so my password cannot be emailed
   to me. I looked through the php_login.php page and I cant seem to sort out how
   the login page is passing the password into MySQL so I can login.

 * rcmullins,
    Next time strat your own thread, your issue is completely different
   from the OP. I know only one way to change your pw in MySQL – here is a guide:

 * I just now noticed moshu’s reply. My apologies for stepping on Mr. Vices thread.
   I didn’t realize how the thread system here worked or how to start a new thread.
   It was an innocent mistake. moshu you may try a unique little human trait called‘
   tact’ next time. And incidentally there are several ways to change your pw, and
   several ways to hash it. cheers.
