 * i intalled time_since plugin. it works good at the main page of my site but after
   activating time_since plugin, i cant log out. when i try to log out, there is
   an error like ; `Warning: Cannot modify header information - headers already 
   sent by (output started at /home/bayrakci/public_html/halil/wp-content/plugins/
   time_since.php:51) in /home/bayrakci/public_html/halil/wp-login.php on line 167`
   
   can anyone help me? P.S. it isnt a problem for only time_since plugin. when i
   installed moody plugin, i got the same error.

 * Make sure there is no space after ?> in your moody plugin document.

 * Whitespace.
    It is always whitespace. /plugins/time_since.php:51 That is the 
   file. [http://faq.wordpress.net/view.php?p=7](http://faq.wordpress.net/view.php?p=7)
