Hi,
My store is running the 1.6 default theme, with the 5-step checkout.
Everything works great...EXCEPT.... when attempting to purchase two items with shipping carriers. In these cases, I click 'Proceed' on the shipping step, and the page simply reloads and does not progress to Step 5 (payment).
The two carriers in my store are custom, nothing complicated. One with typical shipping rates, and the other is purely free shipping for products that don't mail (virtual, event registration - need combinations, that's why).
Again, individually, these carriers and products work just fine through checkout. It is only when going through checkout with, for example, Item A (carrier 1) and Item B (carrier 2) in the shopping cart, that it gets stuck on the Shipping step.
It DOES work with the one-page checkout enabled. I'd rather use the 5-step, however. I do not use guest checkout.
I've tried debug mode, etc, I don't have anything odd installed. No idea why this is happening.
Please help! Any is much appreciated. Thanks.
