Change the URL: it currently says "http://...", but if you add an "s" ("https://...") it should fix it.
Most websites will see that you're on HTTP, and automatically forward you to HTTPS without you having to do anything. However, (presumably because Rogean doesn't have time to configure things properly, and doesn't trust anyone like myself to help) the wiki doesn't.
If Rogean ever does feel motivated, he literally just has to change one line of config:
https://stackoverflow.com/questions/...s-on-all-pages. But until he makes that one line change, we just have to deal with this confusion (and add the "s" ourselves).
