Error when fetching content over HTTPs: "HTTPs server has incorrect certificate configuration"

@Admin can I somehow remove or edit an answer (the link leading to my site?) because it’s not important for this discussion?

Thank you!

Hmm, you’re right, it does seem that flagging might not be available to new users. I can see how that would make it difficult to flag posts.
