Hi all, I recently switched from shared hosting to a Ubuntu 18.04 server. I installed Flarum using this guide and all went well, however, I didn't have SSL so I then followed this guide, which promptly f**ked everything up. So I reset my server, no big deal, I'll just set up Let's Encrypt first, then install Flarum. Well, now I'm stuck on the Nginx Welcome Page. I'm not sure what I can check or if I set something up in the wrong order. I'm pretty new to this all so I don't know where to elaborate, but if you need any more information I'm happy to provide it.
I should also add that I only just noticed that the Let's Encrypt guide is for Ubuntu 16.04, not 18.04. Not sure if that would create this problem.
