I bought a SSL Certificate from godaddy so I could get the green padlock on my domain. They told me that I have to redirect my site to https://tutorspanish.co.uk/ but when I type this on a browser I get the crossed padlock in read which I know more or less what it means but it does not give much trust to my visitors. They said that my domain needs www in other to get the green padlock. But I do not know how to do it
Can anyone send me a guide to add www to my domain and a step-by-step guide to get the green padlock on my site?
