I see a green lock on your website now. Does it work for you too?
If you check the SSL page again and the SSL certificate you uploaded is still in the box, that means the SSL certificate was accepted.
However, note that some browsers, notably Google Chrome, can cache SSL certificates for up to multiple domains. Clearing browser data, restarting browsers, restart computers and restarting network devices does no clear this cache. But you can check your website in Private Browsing mode to circumvent this cache.
