 * Our website has been hit with the most recent hack everyone is talking about.
 * [http://wordpress.org/support/topic/307518?replies=83](http://wordpress.org/support/topic/307518?replies=83)
 * I managed to get the front-end of the site back to normal but the backend/admin
   section is acting very funny.
 * I can not login through the wp-admin.php page whatsoever. I get numerous PHP 
   errors that have never occurred until after the hack.
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/run/public_html/wp-includes/classes.php:1595) in /home/run/public_html/
   wp-content/plugins/postratings/postratings.php on line 861
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/run/public_html/wp-includes/classes.php:1595) in /home/run/public_html/
   wp-includes/pluggable.php on line 694
 * I have checked these files and they are fine. The only way I can login to the
   backend is through the frontend of our website, and then by clicking on “edit
   post” on one of our live post pages.
 * Even when I am logged into the admin, I get this error on the top of every single
   page.
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/run/public_html/wp-includes/classes.php:1595) in /home/run/public_html/
   wp-content/plugins/postratings/postratings.php on line 861
 * I also get tons of errors even when I save options in the admin. They save fine
   though.
 * I dont think there are any script errors but only errors resulting from the hack.
   What are your suggestions on what I should to to fix this?
 * *I have old backups of my wordpress database that I could use for swapping of
   tables but it would be best if I don’t bring back much older information/settings.

 * Also, in the “Create New Post” page, I can no longer view the “VISUAL” tab. It
   only shows everything as HTML.
 * Everything used to be fine yesterday until the headache hack occurred. I appreciate
   any information anyone submits.

 * Re-upload all files – with the exception of wp-config.php and the wp-content 
   folder – using a freshly downloaded copy of 2.5.1.

 * Thanks for the info but what if I heavily modified my files since installation?
   This is mainly why I haven’t done an upgrade.
 * Are there specific files I should be handling instead of the batch of files in
   the folders?

 * In that case, you may need to check every file.
