Simplified html for old browsers


i used to use a shared nextcloud folder to access my epub database from my ebook device (Tolino). I could list and download ebooks stored there.

This worked fine until i recently updated to the latest nextcloud release. Now the browser on the ebook just shows the directory name, but not the contents. Obviously nextcloud now uses html features which are not supported by the ebooks browser.

So before searching for some alternative i’d like ask if there might be some feature/hack/extension which could provide some kind of simplified html for a nextcloud share.
