   you maybe try to help to solve this error? Thank you very much in advance,

 * Hi romanzy,
 * I’m afraid I cannot help you with this problem, as probably it isn’t related 
   to wishlist plugin.
 * “Headers already sent” error shows up when some code prints the output of the
   page before it is expected.
    In its normal workflow, wishlist plugin tries to
   set a cookie for the user, using “Set-Cookie” HTTP header; as another code has
   already sent the page output, and output buffer is disabled on your server, PHP
   trigger that notice.
 * So you should search for the code printing output before it is expected (note
   that also some space or new line character at the end of a file are a valid page
   output )
 * I’m sorry, but I can’t do better than this without seeing the code
 * Hope this helps
    Have a nice day 🙂

 * Thank you very much for your detailed feedback.I truly appreciate.
 * I will check with SeventhQueen, authors of Kleo, to see what they say about it.
