   array in /home/neyofan/public_html/wp-includes/widgets.php on line 654
 * Warning: Invalid argument supplied for foreach() in /home/neyofan/public_html/
   wp-includes/widgets.php on line 654
 * Help please? Thank you. (:
 * Also, when I try to login to go to my dashboard. I just get: Warning: array_keys()[
   function.array-keys]: The first argument should be an array in /home/neyofan/
   public_html/wp-includes/widgets.php on line 654

 * My solution was very simple. for the error
    `Warning: Cannot modify header information-
   headers already sent by (output started at /home/neyofan/public_html/wp-includes/
   widgets.php:654) in /home/neyofan/public_html/wp-includes/pluggable.php on line
   689`
 * In the bottom of the file
 * wp-config.php at the bottom of the file there are two blank lines after the close
   of the php code
 * `?>` in like line 45 there are two blank lines in 46 and 47 , delete those two
   lines and the problem is solved. That is usaully the problem with the “header
   is already sent error message”
 * Hope this helps some people.

 * I had this problem too. I fixed it by saving the design->widgets page.
