No, unfortunately, that doesn’t work in this instance. Going to https://boine.42web.io/wp-admin/ just results in a 403 error.
Did you try looking at the article you were sent before? It has some suggestions as to how you can resolve the issues that cause a 403 error.
And for future reference please don’t blindly use code that was AI generated. AI-generated code contains mistakes sometimes and the AI doesn’t always understand context, so any such code should be looked over before being implemented. In fact, you never want to add any code to your site or other project unless you’ve read it and understand what it will do.
