So I found a small but rather frustrating bug (don't judge by title) in NodeBB.
If you add an IP Ban - no user is able to register, including IP Addressses that are not supposed to be IP Banned, an error occurs well the full html of an error displays saying NodeBB is unable to match the IPs the error message is just an html blob, it doesn't display properly. Initially I thought this could be a cloudflare caused issue so I disabled things like minify, rocketloader, etc and cleared caches on cloudflare and my local system, however the problem persisted, the full html in error message likely wasn't a cloudflare caused issue otherwise other registration errors would also display as full html [Purposely failing the captcha https://i.imgur.com/5XooFnB.png the error displays fine]). However with Cloudflare enabled, NodeBB is unable to match IPs and therefore the IP Bans feature cannot be used. My workaround is to issue IP Bans at Cloudflare Level however it'd be nice if I could use the NodeBB Built in one. Thoughts?
