 * Hello
    I get an error when I try to change my avatar in the phpbb3 forum. This
   error appears when I turn on the integration of connections in WP_united. If 
   the option is not active, the avatar is ok
 * error message :
 * Fatal error: Cannot redeclare validate_username() (previously declared in /homez.
