My current site is running 1.4.1 with very heavy core edits we did in 1.2.3 some 3+ years ago. But we faced issues that we could not fix without a fresh install and we did this. New install, copied the DB and then copied each needed module / design etc
All good besides 1 thing, we cannot set UPS negotiated rates in google checkout, and I searched the boards and there seems to be no resolution?
My dev says to do a core edit id 1-2 pages and we are trying to avoid a core edit. Has any one attempted or interested in creating an external module or can we get magento to do this as they did with paypal and auth.net pass on?
