When i click "Complete Order" button, it doesnt display the order number page and instead displayed "Internet Explorer cannot display the webpage" error.
I've added the following in the configuration.php page:
$display_errors="on";
And when i click the "Complete Order" the next time round, i got the same "Internet Explorer cannot display the webpage" error. And when i refresh it, it shows the following line error at the top of the page:
Warning: Invalid argument supplied for foreach() in /home/pessimiz/public_html/billing/cart.php on line 0
It is still working before i added the server settings in WHMCS as well as the Products/Services section.
Can anyone please give me any advise ?
