Custom No longer sees orders

Customers on a client's site can no longer see the orders. I've confirmed this on my admin account with test orders.

Hello,

That's weird, can you test it with one of default Joomla front-end template so that we can see if it works fine with it ? Thank you.

Also, note that the notice message is actually coming from your template.

Yes, I'm aware that error has to do with the template. I just thought I'd include it because it was the only error. Yes, switching to Prostar I see everything, including the prices. What about the template causes the prices to be $0.00? Also, the client still is using php 5.6.30. Is this a contributing factor?

Keep in mind, this is the same template they've had for nearly 5 years.
