 * 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!

 * 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.
