I have been trying to watch a HTML course but I cannot get any further than the free lessons that are on offer. I want to sign up and watch the full course but whenever I click the sign up to this course button, the site takes me to a new window with a 403 Error saying that the server is not secure and that I may be vulnerable to attacks.
Any reason why this is happening? It was working fine yesterday, unless there is an issue with the Envato servers?
Any help/advice would be appreciated.
