What site? What security software are you running?

kristyn@lilluna.com via n.convertkit.com is the site & I use Webroot.

Hi

This support article should help:

Unfortunately, not. Thanks anyway.

Is this the site? https://convertkit.com/

I guess the blogger does use that service.

Where does this link come from? n.convertkit.com

For S&Gs I joined the site and see nothing that starts with n.. I see app. see screenshot

Interesting... I see this https://lilluna.com/author/kristyn-merkley/ for the person you're referring to on WordPress hosted site. Where does the n.convertkit.com come from. You should provide steps to replicate how you get to the converkit.com site.

You should also post a screenshot showing the issue. Did you disable Webroot, reboot the computer, and try again?
