I use a dynamic list wizard with ADDT for a backoffice. On my computer,with phpmyadmin, everything is ok and seems to be functional. But as soon as I upload my folders I got this error message :
Warning: Cannot modify header information - headers already sent by (output started at /Library/WebServer/Documents/backoffice/Connections/connec.php:1) in /Library/WebServer/Documents/backoffice/includes/common/KT_functions.inc.php on line 464
I checked my pages and didn't notice "white spaces" before or after php markup. I always got this problem.
Anynone could help me ?
