Don’t combine problems. I can’t quickly see what’s happening here, as there’s discussion of WordPress, default site, and Virtualmin login. Please focus! One problem per topic, so I can drop in and figure out what I’m trying to solve quickly.
I’m gonna pick the Virtualmin problem to talk about, since that’s what’s in the title, and ask you split other problems/questions into their own topic with a reasonable title. (Also see forum guidelines.)
NS_BINDING_ABORTED indicates the request load was canceled, and it seems like it can show up in redirects: Re: NS_BINDING_ABORTED - Boris Zbarsky - org.mozilla.lists.dev-tech-xpcom - MarkMail
I don’t think it indicates a name server problem.
We sometimes see weird issues like this when folks have configured Webmin to run behind a proxy, but that doesn’t seem to be what’s happening here, at least not intentionally.
Have you tried a different browser, one without any extensions enabled? Also try a different network, if you can.
How’s memory? It’s plausible (though I haven’t seen it) that some background processes might get killed by the OOM killer, which would prevent them from ever sending data back…the dashboard is relatively heavy, as it’s pulling data from a bunch of different sources. It’s mostly cached, but it’s still going to spawn more processes than almost any other page in Webmin/Virtualmin.
