<!-- Copied from: https://github.com/fooman/totals-sorting-fix/blob/master/app/code/community/Fooman/TotalsSortingFix/etc/config.xml
This is to fix calculation errors when there are multiple custom totals -->
<tax_subtotal>
<after>nominal,subtotal,msrp,freeshipping</after>
<before>tax_subtotal,weee,shipping,tax_shipping,discount,tax,grand_total</before>
</tax_subtotal>
It looks like the following section from
app/code/community/Mollie/Mpm/etc/config.xmldoes more harm then good:When this section is present no Shopping Cart Price Rule seems to work.
When removing this section the rules start working again.
