So, basically all I want to do is buy some things online, but the problem with the site that I'm buying from is that when I click on the 'add to cart' button which runs the javascript command I get the: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/gnsellco/domains/seller1.com/public_html/shopcart.php:1) in /home/gnsellco/domains/seller1.com/public_html/shopcart.php on line 6 Output has already been sent to the browser at /home/gnsellco/domains/seller1.com/public_html/shopcart.php:1. Please make sure the command $xajax->processRequest() is placed before this. error. Is there anything I can do to get around this short of getting on to the owners of the site and getting them to fix their code? Thanks heaps
