For example, I am using the module nodebb-plugin-custom-pages and created a page called home.tpl and route /home, now if I change home page to a custom url /home and navigate to home page, it opens up /home but it is still visible in url. While setting it up to popular, /popular does not show up in url.
When "community.nodebb.org" was updating, nginx servered a "502 Bad Gateway" text error page instead of a custom page displaying something like: "We will be back soon". I recommend that NodeBB creates a static page that is directly servered by nginx when NodeBB is down. This page should use the exact same theme as you currently have selected for your site. I think the link to nginx should be automated as much as possible (maybe ask [yes]/no permission in setup). But if it can't be there needs to be an easy tutorial on how to link nginx to this static page. The static page should be able to be overridden. It should be updated every time the theme changes. Thoughts?
