I'm going to have to table this for a bit; that freeoptions shipping method is making my head hurt.

That's why I gave up on trying to find a solution for the freeoptions shipping module and instead worked things around it. But my solution for some weird reason doesn't work with OPC and I don't know why.

Thanks for trying. I really appreciate it.

I have a weird problem and am hoping someone can point me in the right direction...

ZC 1.5.6, OPC 2.1.3, php 5.5.38

Using PayPal Express and Guest Checkout sometimes comes up with a blank shipping address. Keyword is sometimes and I can't figure out why - the only common factors are PayPal Express and Guest Checkout. It does not happen all the time, so we do have guest orders using PayPal Express and it's all good.
We tried disabling PayPal Guest account (in PayPal account settings), and have tried disabling the PayPal shortcut button on the login page - made no difference.

One thing I did notice (although possibly just a coincidence) is that there are 0 orders using PPE with Guest Checkout and different billing/shipping addresses. We do have PPE and different addresses, we do have PayPal Pro and different addresses, we do have PayPal Pro in Guest Checkout with different addresses, but not one PPE in Guest Checkout with different Shipping and Billing addresses. Maybe just a coincidence?

Any ideas? Where do I start? I have both PPE and OPC debug on, but didn't notice anything relevant. TIA

@balihr, besides the PPE/OPC trace-logs were there any debug-logs thrown an/around the time of the missing shipping-address(es)?

Depending on the site in question, i.e. how 'buggy' it is, you might consider installing Report All Errors and setting it for all non-duplicate-constant messages on the storefront. That way, if/when the issue occurs again, there would be additional breadcrumbs left to hone in on the issue's source.

BTW, which sub-version of zc156 is in use?

[balihr]

Thank you, Cindy.

No other logs were thrown that I would say are associated with checkout. We do get a few related to duplicate language constants, but I don't think that has anything to do with the issue described.

I've installed Report All Errors and will start watching it now, maybe that will take me somewhere. I'll report back when there's some data.
As for how "buggy" it is - I built that site so... uhm... okay, I'm ready for a huge log file...

It's ZC 1.5.6. Period. No sub-version, just 1.5.6

I did it!
Found a way around it and it works with OPC thanks to Ajeh and this code https://www.zen-cart.com/showthread....70#post1240770 from where I got the idea. Perhaps it isn't elegant but it accomplishes what I need.

This little piece of code prevents the checkout buttons from appearing if free shipping (from freeoptions) is used in conjunction with reward points and if the cart total gets below the minimum amount for free shipping to kick in. But it allows the selection of a different shipping option.

Adding the code in red to templates/tpl_modules_opc_submit_block.php

In regards to the Coupon, Reward Points, and Gift Certificate. Every time the APPLY button is hit to update the data on the shopping bag, the only message generated is "Please confirm the terms and conditions below." without acknowledging either coupon code, reward points or GV code were accepted at all or generated some errors.

Would it be possible to generate the appropriate messagestacks for each of these? and if so how?
