Website Security – Shows My Website is Not Secure


I just went to my website and at the top of my screen by the url, it showed a lock with a slash through it and said my website was not secure. It also said if you login to this website, your information could be compromised. I don’t think it has ever done that before, so I was wondering if someone could take a look at it or if someone had any idea why it isn’t secure anymore… thank you!
