One-Page Checkout [Support Thread]

That observer is making a call to OPC's session-based class ... which has mysteriously "gone missing" sometime between load point 75 and 131. I'll be home next Monday and will take a deeper look.

Ah I see. Was hard to replicate, but definitely when going through lots and lots of items. Otherwise, it seems to be okay.

I think latest update has the above fixed as it mentions 'continually load classes'? Thanks very much, will give it a go.

I need to force a specific shipping method (shipping by quote) for not only customers in a geo-zone specified in the shipping by quote shipping module but also for customers in a specific customer group regardless of their geo-zone. How can I do this in OPC? A notifier suggestion would be a big help.

Thank you!

Sorry, I found an article here that provides one way to do what I need.

I have also seen the "Call to a member function guestCheckoutEnabled() on int" error in ZC 2.1.0/OPC 2.5.4.

I have also seen the "Call to a member function guestCheckoutEnabled() on int" error in ZC 2.1.0/OPC 2.5.4.

Unfortunately, that's meaningless without the full log with the backtrace and the page on which it was issued.
