I'll see if I can explain this so there isn't any missing pieces. I upgraded our wordpress/debian 7 install to debian 8 and then to debian 9. At some point in there, not sure as I cannot recall if I tested the site working or not before moving on to debian 9 upgrade, the site is working but doesn't display anything below the main www.
I thought it had to do with permalinks inside Wordpress but that didn't fix it. Thought it could be a sites-enabled issue, that also was not the case. I am not sure where to go from here. From what I remember of websites, if you can get to the main site you should be able to get to the whole thing but I'm guessing not.
What am I missing?
Sounds like something in Apache to me. I know that isn't too helpful but it could be several things
@FATeknollogee rolling means they constantly upgrade sw when ready. The opposite is sw which sticks at a given version and is subject to security fixes only.
Exactly. In Windows terms, it would be like MS Office updating from 2013 to 2016 automatically on any given day. Tumbleweed tends to update a couple times a week, but the updates are tiny. Just whatever applications have a new release and have been tested get released as they are ready, not in blocks together.
The big difference is that it is updates to packages and releases of new packages as they are available, not just patches that are provided. All OSes release patches on a regular basis as needed, or weekly. But rolling releases actually update the software versions all the time.
