One-Page Checkout [Support Thread]

[linuxguy2]

Hi, I have what seems to be a minor bug to report. I'm running OPC 2.0.5 and ZC 1.5.6a, with the latter's shipping module set to Zone Rates. In guest checkout, when I enter a billing address in one country, then uncheck the shipping=billing box and enter a shipping address in another country, the shipping charge quite rightly changes to the amount for the second country. BUT, if I then change my mind and re-click the shipping=billing box, the shipping charge remains stuck at the amount for the second country. (Note that this glitch does NOT happen if I log into an account instead of doing guest checkout.) Anyway, I realize the situation is one that will almost never arise in real life, but it came up while I was putting the plugin through its paces, so I thought you would want to be aware of it. In any event, thank you for designing a very useful product!

On the OPC admin page if you have "Enable One-Page Checkout Debug? Full" you should be getting PHP notices/errors in the Logs. (Two places System root / and your cart root.)
You may already be aware of this but OPC is being update. You might review some of the latest unreleased fixes for 1.5.6a noted here.
