Okay so I tired that and it didnt work either.
I have a testing environment for stripe.
After signing in you can log on to this url
https://saritoria.com/my-account/my-wallet/
And click connect to stripe. Add this your credentials and see if it works. I can’t give you stripe credentials as it requires google auth code. However, you create an account. Add in dummy credentials and see if works.
I tried everything but its whenever the xtheme core plugin is activated I get this error.
