Your problem
My problem is: Unsuscribe links sending to 500 Internal Server Error
These errors are showing in the log:

Steps I have tried to fix the problem:
I have been playing with the preferences of email settings and clearing cache. Following this video: https://www.youtube.com/watch?v=JdgVdiv1JhU
I think it is an error related to Mautic Update because it did not happen before. I realize because a contact notified us that he could not unsuscribe.
