One-Page Checkout [Support Thread]

[bumba000]

We are running zc 2.2.2 on php 8.2 and opc 2.6.2 now with some modsecurity rules disabled. most folks having no problem now, but we just had another that for some reason got a 500 server error during checkout. placed an order twice and still had the items in his cart. Is this possibly a common issue? Would it be resolved by upgrading to the 2.6.3 version. Also this is all with authorize aim.

If I'm to upgrade, should I just overwrite existing files, or is there db stuff as well? Should I use the plugin manager to uninstall and re-install?

Thank you,
John

FYI,

Files come down as 4.6.3 vs 2.6.3

Thanks for that; the upload's been corrected.

OPC is not yet an "encapsulated" plugin, so the "Plugin Manager" doesn't participate in its installation/removal. You'll need to use the just published v2.3.6, which corrects a couple of issues.

OPC's readme.html identifies how to install/upgrade.

I just received the following warning. It is my first time to see this warning.

I'm seeing how to "patch" this, but I'm having a hard time determining where the 'telephone' element of the billing address disappeared to.
