 * For some reason, when I try to activate plug ins, I get this error message:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/leah21/public_html/wp-content/themes/Chick Lit Reviews and News2/functions.
   php:79) in /home/leah21/public_html/wp-includes/pluggable.php on line 934

 * I’ve never gotten it before and I haven’t changed my theme at all from what it
   was. Is it just a simple error? My plug in does activate and I just have to go
   back, so it’s not a massive issue, but I’m just wondering what the fix is?
