按了BUY后Warning: Cannot modify header information - headers already sent by (output started at /home/bestinkc/public_html/includes/languages/english.php:641) in /home/bestinkc/public_html/includes/functions/general.php on line 33

solution:
The problem is that many editors seem to add additional blanks (spaces) and/or empty lines at the end of a file when you edit it.
edit includes/languages/english.php, remove the blanks at the ending.
