Test the install.

Get errors again...
I would have to look at what is going wrong to see if there was a non generic tracer in the error log perhaps. Or force an error to see if there is an old reference on the server. Next I would try an older API version just in case the 'newest' one had a bug. And then start checking if the server version and PHP version mismatch along with the older PHP bridge these servers use is faulty.

You could post the error log get more eyes on it or hire that Twitchtoo guy to have a look - coffee is always a good place to start!
Thank you for taking the time! So last night after business hours, I did as you suggested, and nothing changed. I deleted the module, reinstalled the module, I changed the API versions (went through each and everyone of them testing for errors along the way), nothing. Entering the wrong CC data triggers the error as it should, once the CC data is reentered correctly the error message is not removed, the customer cannot move forward with checkout. No log errors generated either. Refreshing the page is the only way to get rid of the error message generated however customers wouldn't know that and instead walked away. I've had months of abandoned shopping bags I had no idea about, until one customer finally brought it up a few days ago. And I was all these months wondering why my sales had tanked.

I will definitely upgrade ZC after the holiday season is over (heavily modified store www.byvalenti.com, so not an easy task to accomplish before Christmas )

PHP Version on my server is 7.3.33, which should be ok for ZC1.5.6c.

The other thing that I can think of as a "patch" of sort, is to auto-refresh the page after the message is generated (?) I know I'm making you cringe right about now, I apologize about that. With my very limited knowledge of php, I've made quite a few here cringe over the years.

Can I invite you for coffee to take a look see if you could figure out a temporary solution? No emoji for coffee but this would do
