1.5.2.1 Checkout Problems

Hi,

Checkout gets stuck at step 2 or 3, unless new address is inserted during the process.


UPDATE: Silly issue discovered, on step 3 the predefined address needs to be selected, if user does not select the address, it does not throw warning or errors. How to by default set the selection????

Have you made any upgrades recently? I would recommend actually fixing the problem at hand instead of putting a bandage on it. Have you upgraded recently? I would just re-upload a fresh copy of the entire checkout folder both control and view. If you have a custom theme then you will want to be careful.
Attached are the folders. Just upload the entire contents to your installation root.
For 1.5.2.1: Hope it helps.
