It's just a browser warning that the site is using outdated encryption. I saw some chatter about an update coming that should fix it. Generally these types of messages come from the web server settings rather than the site software (like vBulletin), where TLS 1.2 needs to be enabled and older versions (TLS 1.1, TLS 1.0, SSLv3) need to be disabled. I went through changing these settings on a few servers at my company a couple years back because they got flagged on a security audit. It's more of a nuisance here than an issue, because there isn't much sensitive information going around (like credit card payments, etc). Newer browsers just throw that warning out there and for now allow you to bypass it to get to the site anyway.
