"Unknown error encountered. Please try again!" is thrown on the page upon clicking [Confirm Order].

I don't see where I can enable Fast Checkout in the Authorize.Net payment settings?  (the browser tab reads "Fast Checkout" if that matters)

System Log shows: 2024-05-02 15:00:16 - Unknown Error: AbanteCart core v.1.3.3 Class "net\authorize\api\contract\v1\MerchantAuthenticationType" not found in <b>/home/outdofjroductsg/public_html/extensions/default_authorizenet/storefront/model/extension/default_authorizenet.php</b> on line <b>36</b>

I have a system message:

/home/outdofjroductsg/public_html/index.php file is writable. It is recommended to set read and execute modes for this file to keep it secured and running properly!


I'm not sure how to get to the system files in the hosted environment, though.

I'm also not sure what I'm looking for in the browser console, to be honest.

Thank you for your help!

I'm trying to run my first live transaction.  Authorize.Net + Zen Payments. Receiving this nondescript error and I don't now how to debug!  Any guidance for me?  Thank you!!

In System/Settings/Store Details the Default Tax Class is set. Is that what you are referring to?

Cleared cache.  Logged out.  Cleared browser history.  Logged back in.  Added appropriate zip code and clicked [Estimate] shipping and taxes...  A section below flashed and disappeared without updating taxes.

Is there a step I may be missing?

Hello. I'm a newbie.  First time poster. 

I need to set up my taxes so I only charge sales tax on one state.  But the instructions aren't proving to be very helpful.

Do I create a location for this state, then a Tax Class for this state?

OR

Do i choose Location=USA, unselect "all location zones" and pick my state from the from the drop-down? 

FWIW, when I test, I don't see sales tax calculating and/or showing up in the checkout experience.

Thank you for your help!!
