'I was sent a link that goes to a learning site by my future employer to take some online classes via email. Every time I try to access the site I get a message that I need to close the page as the website may be impersonating someone trying to steal my information. I use Safari, not that I have a clue what it means, is this a restriction issue I need to avoid or sidestep like a firewall or something similar? I tried typing the web address and the HR office says not to do that - to only use the link. How can I check what’s wrong so that I can take access the online classes for this position?
