Checkbox shipping = invoice address doesnt work

I have a site that is having the same issue when they select shipping address to be the same as billing. However they are just brought back to the checkout page. Un-checking the “same as” box does nothing to fix the issue. If you fill out both the Billing and Shipping address fields the first try you are taken on to the Gateway. PayPal in this case.

i have also problem with this checkbox :

i have upgraded from 3.8.8.1 to 3.9.1

– in 3.8.8.1, when the checkbox was checked, fields under was hidden.
– in 3.9.1, when the checkbox is checked, fields under are not hidden,
and i have this jquery error :
“Uncaught Error: Syntax error, unrecognized expression: :not( .checkout-heading-row, :has( #agree ), :has( .wpsc_gateway_container ) )”

this error come from : wspc-core/js/wp-e-commerce.js line 519

i found a very bad mean to arrange this, i replace line 519 by :

var billingInfo = jQuery( ".wpsc_checkout_form_11, .wpsc_checkout_form_12, .wpsc_checkout_form_13, .wpsc_checkout_form_14, .wpsc_checkout_form_15, .wpsc_checkout_form_16, .wpsc_checkout_form_17" );
billingInfo.closest( "tr" ).hide();

Someone know a best mean to arrange this ?

If you use chrome enable the console and look at the Network tab.
When you click the shipping same as billing option there should be an ajax request fired.

Or if you have copied the checkout theme file for WP eCommerce in your theme then try renaming that so it uses the default one and try it again.

Most of the times its caused by outdated theme files.

i tried, but there is no ajax request, in network tab
it seems there is the error (“Uncaught Error: Syntax error, unrecognized expression: :not( .checkout-heading-row, :has( #agree ), :has( .wpsc_gateway_container ) )”) before, who bloks

See if in your theme directory you have this file: wpsc-shopping_cart_page.php
If you do then rename it to something like wpsc-shopping_cart_page.php-OLD so that the plugin will load the default one.
After you rename it flush the theme cache under Presentation on the right side under Advanced settings.
