Yes, that is the way the continue shopping button is designed to work. when you press the add to cart button, it saves the name of the page you where on to a session and the continue shopping button uses that session when it is pressed.
f you wish to over ride that, edit the continue shopping code block it will look like this:
<?php
// WA eCart Continue Shopping
if (isset($_POST["eCart1_Continue_100"]) || isset($_POST["eCart1_Continue_100_x"])) {
$Redirect_redirStr="";
if (true && isset($_SESSION['WAEC_ContinueRedirect'])) {
$Redirect_redirStr=siteToPageRel($_SESSION['WAEC_ContinueRedirect']);
}
if ($Redirect_redirStr != "") {
$eCart1->redirStr = $Redirect_redirStr;
}
$eCart1->cartAction = "Continue";
}
?>
change the following line:
$eCart1->redirStr = $Redirect_redirStr;
to hard code the redirect page name:
$eCart1->redirStr = "products.php";
