 * I get
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/innathil/public/html/wp-config.php:1) in /home/innathil/public/html/
   wp-includes/pluggable.php on line 897
 * when I try to access my website. I checked the wp-config file and there’s no 
   empty space. I don’t know what to do.
 * Thanks for help.

 * Hi Esmi,
 * Thank you for your reply. I already tried that one and it didn’t work. Do you
   have any other suggestions?

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Ten theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.
