migrated site and now have many errors

[RonGin]

HI, I have changed hosting form A2 to HostGator and now when I check out i get error on checkout and sometimes on sign in.  I contacted stripe and they told me that it is a problem with the module but I don't see how? Any suggestion?

Thanks Ron

Well, the error message says 'Expired API Key provided' --> that's the message that stripe server responded with. You should log in to your stripe account and generate new api keys
