We were previously running a Discourse multisite setup with around 22 different forums. Recently, we decided to remove the multisite configuration and keep only the default site: Default site now: forum.mamapedia.com Removed old multisite domain: forum.employ.com (and 21 others) The Issue: Even a…

You need to switch to a standard install . The stuff you’ve done to make it be multisite is to make it possible for the server to serve a bunch of domains. If you make a new server and restore the backup then you can’t break anything since you’ll just switch back to the old one. The only catch is t…

Thanks @pfaffman , We attempted to switch from a multisite setup to a standard install , but the issue still persists. What We Did: Removed the Discourse Installation: Deleted the entire /var/discourse directory. Reinstalled Discourse: Cloned the Discourse repo again. Recreated app.yml with t…

[图片] Abdelrahman MoHamed: Recreated app.yml with the necessary configurations. Did you run discourse setup or do it by hand? Do you have the ssl and let’s encrypt templates? If you ran rebuilds a bunch of times with the orange cloud you could be rate limited

The reason this is happening is simple. Multisite will select a forum based on hostname. A non-multisite install will happily accept whatever hostname you point to it. So as long as you have all the old hostnames directed to that install, it will serve the remaining site on all those hostnames. […

OMG. I don’t remember the last time that I disagreed with you on a matter of fact. As a rule, when I see your avatar in a topic that I’ve commented on, I know that I’m going to learn something! [图片] Richard - Communiteq: The reason this is happening is simple. Multisite will select a forum base…

[图片] Jay Pfaffman: I know that I’m going to learn something! Well TIL that I should update my facts more often! That code has been there since 2014 so I guess I was living waaay in the past. You’re completely right, it will redirect.

Thanks @RGJ , @pfaffman , We have checked app.yml, and there are no custom redirect configurations or overrides. However, our instance still isn’t redirecting unknown hostnames to the main domain. Nginx Configuration: Is there a way to verify if the redirect logic from templates/web.ssl.template…

[图片] Richard - Communiteq: Cleaning up your old configuration is not a workaround, it is the solution. Here’s a pointer.

Do the old domains all have the orange cloud turned on? Does riding off the orange cloud solve the problem? If so, then, as I expected all along, Richard is right and you need to clean up your setup. But if using cloudflare allows a bad actor (you in this case) to serve someone else’s site on their…

OK should I run ./discourse-setup after downloading discourse or should I paste my old app.yml after downloading and then run ./launcher rebuild app Which path should I take ?
