Security

Hellow, I bought a SSL for the url endoflifepro.org so it will have https//…. so people feel safe and it handles it to a certain extent. but someone today did not register with my site because this warning came on from their computer. they told me:

“…Hi. Just to let you know that when I went to register, and also subscribe to the newsletter I got a security warning from my McAfee software that suggests that the ELPC site is risky.
McAfee WebAdvisor
Warning: Trouble ahead
Whoa!

their comment to me was that it’s possible that the way the site is configured may let other people jump on board that shouldn’t. What else do I need to do? is this issue above related to the issue that I’m sending you via an attachment “not secure” I bought a SSL certificate and I thought that would handle these types of issues. its only when they are within the categories page that you see this “not secure” in the url tab. why is that?

is this issue coming from the same issue?

thank you for your help! I want people to trust my site.
