One-Page Checkout [Support Thread]

[strelitzia]

Zen Cart 1.5.7b
OPC 2.3.7-beta2 (2021-01-17)
PHP Version: 7.1.33
Shipping modules used: Storepickup, Advanced Shipper

Any suggestions as to why this message is frequently displayed when going through checkout?

"It's taking a little longer than normal to update your order's shipping cost. Please close this message and try again. If you continue to receive this message, please contact us."

Sometimes it has to be closed 2 or 3 times before you can actually complete checkout.

That's the result of having a 'number of' shipping modules (e.g. USPS, UPS and FedEx) where the quote-generation latency gets long. You can control the timeout via configuration of the Update Shipping AJAX Time-out setting (defaults to 5 seconds, which is a ton of time).

The shipping isn't using ANY external shipping methods. They are all methods set within Advanced Shipper for specific locations, weights, and order values. I don't really understand why it's doing this as the shipping cost is displayed next to the various checkboxes as soon as you get to checkout. There is no delay in the method cost being displayed on screen.

That's bizarre. Are there a ton of logs being generated?

I'm seeing instances of this in the log directory, although I don't yet know if that is being generated at the same time as the Ajax timeout occurs
PHP Notice: Malformed value for session-based shipping module; customer will need to re-select: false in /home/mysite/public_html/includes/classes/order.php on line 323
I recall reading that others have experienced this error log and it may be a ZC bug?

Also seeing a few instances of this:

It'll help if you could enable the OPC debug so that you can capture what OPC thinks is going on when the issue occurs. You can either make the associated log available via link (the files get too large to post in a response) or send me a PM and I'll let you know my direct email to which you can send that output.

It's now enabled. I'll let you know when I have a log where this issue occurred.
