 * I made two interface for my society website:
 * a french one at fatstep.com
    and an english one at fatstep.com/en
 * each interface has its own sql base.
 * They both have been installed with french version of wordpress, I forgot that
   i could simply take an english one to make the english interface.
 * …
 * Yeah, I know…
 * In consequence I modified some files to make the registering and the user profil
   in english but it didn’t work.
 * Now the english version is broken with these fatal lines that I cannot repair:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /homez.99/fatstep/www/en/wp-config.php:1) in /homez.99/fatstep/www/en/wp-content/
   plugins/theme-my-login/classes/class.wp-login.php on line 38
 * and
 * Warning: Cannot modify header information – headers already sent by (output started
   at /homez.99/fatstep/www/en/wp-config.php:1) in /homez.99/fatstep/www/en/wp-content/
   plugins/theme-my-login/classes/class.wp-login.php on line 468
 * Of course I can’t access the dashboard and under internet explorer the view is
   horrible.
 * This is the working interface, the french one:
    [fatstep.com](http://fatstep.com)
   and the broken one: [fatstep.com/en](http://fatstep.com/en)
 * I hope I can repair it!
