Internal Server Error – (Uncaught Error: Call to undefined function incr_desr())

Hello best team,

When I try to place an order, I get the message “Internal Server Error”. I didn’t have this problem before. I don’t know if it’s because of compatibility with another plugin? Where is the problem?

Below is the information from the debug log. How can I solve this problem?
