Getting a critical error on site health when running Cost calculator

Hi,

I’m getting a critical error on site health when running Cost calculator.

The solution suggested here https://www.ads-software.com/support/topic/getting-a-critical-error-when-running-cost-calculator/ does work but it would be good if the developer could sort this out on the next update.

Unless anyone has a more permanent fix they could suggest that doesn’t involve always manually updating the code?

Cheers
