For the include to work, you either have to have the include files in the default listed in the php.ini file (which my provider does not provade access to) or specify the full path to the file. So locally my includes look like:
include ('mysql_connect.php'); (which c:\sokkit\includes is the default include file)
But when I upload the files it has to change to:
include ('/home/site/domains/domainname/public_html/includes/mysql_connect.php');
or the links break. This gets tedious because I tend to use a lot of includes in my scripts so I can make easy global changes.
