I'm sorry, it took much longer than expected to find time to answer.
We are currently running MLF on 2.4.24, and it is running great, but I really like the way this MLF forum here displays on mobile. I've updated a test version of our site to 20220803.1, but it doesn't look nearly as good as this site. Is there a step I'm missing after the upgrade related to templates or other to better mimic MLF here?
Generally there are no new ressources except the icon
Everything else (that belongs to the theming part) are only changed files. So the first attempt should be to reupload all files of the theme (themes/default/), to remove the files from the sub directory
templates_c and to reload the page from the server (on a desktop system with
[CTRL]+[F5]). If that doesn't fix the problem, I would like to ask you for a link to the test system so I can look at it directly.
