   I just activated a new theme and I got the following warning:

   Warning: Cannot modify header information - headers already sent by (output started at /var/www/vhosts/despekbraander.nl/httpdocs/test/wp-content/themes/ruinerwold/functions/theme-options.php:317) in /var/www/vhosts/despekbraander.nl/httpdocs/test/wp-includes/functions.php on line 862

   what is going wrong?

   you have some sort of issue on line 317 of
   themes/ruinerwold/functions/theme-options.php

   Often, the cause is white space between, before or after php tags

   thanks for your answer!

   Can you look at my code because there is no line 317 :S

   YEAH! Rev. Voodoo, I just deleted the last rows after the php tag and the error is gone!

   Thanks for helping!

   THere actually is in the paste, and that is the problem!

   lines 306-317 are white space after the closing php tag

   there should be absolutely nothing after
   

   <?php } ?>

   no blank lines, not even one empty space after that >

   And in all honesty, that last line could read
   

   <?php }

   eliminating the unnecessary closing php tag, and getting rid of the whitespace issue in the first place
