Hi @farfade, did you have a previously working setup? I would think it should still work.
If you are starting fresh, another user in the past previously used a guide on the web - I just confirmed it is live still. I would pay attention to just section 5 as everything else is outdated. I have not tested to see if this will currently work but if you’re using Apache on your own hopefully you are comfortable with Apache.
Maybe your files need to be accessible by the apache webserver user.
