One-Page Checkout [Support Thread]

[lat9]

An odd error occurred overnight where an error in OPC caused duplicate orders 22 seconds apart for the same customer and same items, but did not send out any order conformation emails. Only one of the orders was charged out (PayPal) with no payment confirmation visible in admin, but shows in PayPal.

Same error posted to the log for both orders.

What other plugins are installed for the site? I'm also assuming that you're running zc157c ... or a fully-patched version of zc157.

The site's "Raw Access Logs" can also be your friend here. Since you know the IP address and timeframe, you could search those raw-access-logs for that IP address to get a feel for how the customer navigated through the site.
