[OpenCart] Checkout Error With Payment Gateway

Job ID: 32056671

Budget: $10 – $30 USD

Hi! I use this gateway to process my checkout:
https://transbankdevelopers.cl/plugin/opencart/

After a server update it no longer works, maybe it is necessary to configure PHP elements or correct something, I really do not know.

I am looking for a specialist who can diagnose and solve the problem, I am attaching some screen prints.
