I found a securtity script online and i wanna combine it with my shoppingcart system. the security script requires me to put one php include as the first line of every page i wanna secure, as simple as it gets. Unless you get these damn header problems.
I think the problem is caused by the fact i try to submit the headers twice. Once in the main file and once in the file i included. So in one page hes trying to send the headers twice. If i delete the headers line in the include file the security system doesn't work anymore, if i delete the headers lines in the mail file the cart doesn't work anymore. Does anyone have a clue how to solve this? I posted the includefile and the errormsg below.
Thanks
