after login, there is an attempt to load roundcubemail/assets/program/js/jquery.min.js but that fails with 404.
Without jquery, the hamburger menu does not open, and other functionality is also not available.
I cannot find that file jquery.min.js in the tarball.
I checked the rpm in Fedora, and it seems we have to use the -complete tarball from https://roundcube.net/download/

Any suggestions?
