   When posting not logged on WordPress or not saying any website, this is the error you get:

   Using Unknown on Unknown O.S.
   Warning: Cannot modify header information - headers already sent by (output started at /home/site/public_html/wp-content/plugins/useragent-spy/useragent-spy.php:508) in /home/site/public_html/wp-comments-post.php on line 79

   The comment is posted anyway, but the page loaded is that error.

   Did you modify the plugin's code?

   It's quite a common error when there's a newline or spaces at the end of a PHP file. Search Google for: Cannot modify header information - headers already sent
   And you'll see what I'm talking about.

   Thanks for using the plugin!

   Regards

   My client also gets these messages. Ofc, i can suppress warnings, but in the mean time, it would be nice if the code can be adjusted, or a detailed solution can be posted.

   My client nor me have changed the code.

   Thanks a lot.
   Regards
   Kim
