Tracking page stop working after last update

Hi! I need help with my website.
Some of my customers were having trouble tracking orders. The tracking code was reported as invalid. We use trackingmore as 3rd party service to track shipment. All new tracking codes showed as not found. I switched the service to Cainiao, but the problem got worse, as even the tracking codes that worked before, stopped working. All showed as not found. So I tried to update the plugin to the latest version but now the tracking page stopped working completely. I need help.

Thank you!
