I was using a Treo, and the theme was fine. Then I switched to a Motorola Q and I only get the Title, nothing more. Login is the same, but the Virtualmin Mobile Theme interface only shows the Title.
The Q is running WM6 CE and it's a smartphone, not a pocketpc like the Treo. IE seems not to work as well, because some sites I have set up with alternate handheld.css stylesheets which worked fine for the Treo get no CSS styling at all on the Q. Which sucks, but it's good to know that it sucks so I can fix it for the loads of folks who are running WM6 CE now.
I changed to another theme (Stress Free) for mobile to see if it would show up, and it did indeed.
So, I switched back to Webmin Mobile, and it was hit-or-miss... mainly miss. The first time I tried it, it seemed to be working fine, but maybe that was because the pages were cached for the other theme? But it did look like VM Mobile theme, and it did show the proper VM Mobile index page.
It works as expected from my desktop and laptop on https://m.domain.tld:port##
Not sure what to think... maybe I'll try using a simpler non-framed themes if there is one.
It doesn't seem to be a problem for the server to deliver any of the other themes to my device, and it must recognize the browser agent, because it definitely delivers whatever theme I spec for mobile... except for the actual mobile theme, which only renders
Virtualmin 3.57 on hostname.net (OS Linux version)
However, when I refreshed and went again to the index via https://m.domain.tld:port##, all I get is the Title of the page, and no content.
