Opencart Version: 3.0.3.1 - Square Extention - errors out with ‘redirectu_uri’ invalid value

For Opencart Version: 3.0.3.1. The Square Extension stopped working on my website, but it had worked fine before. After re-installing new credentials for Square it would not connect to Square and errors out with ‘redirectu_uri’ invalid value. I tried re-installing the extension fresh and it did not fix the problem. Anyone else seeing this issue?

Thanks
Frank

Doesn't seem to be related to OpenCart. Check the Square extension settings.

thekrotek you were correct, I need to understand how to read error messages...jeez. I did not properly copy the Square OAuth Redirect URL into the Square Developer Portal! Thank you.
