Hi Glenn,
Sounds like some big changes afoot. @ross might correct me on this, but from memory, whilst mod-rewrite is used in Gibbon, you’ll most likely not notice if it is not enabled. However, it does provide some protection to some files that you might not want people to access (e.g. database structure), and so it is useful to have. These same documents are available elsewhere and not very sensitive, as Gibbon is open source, but this makes it a little hard for students to find them.
My aim would be to get all of the required modules set up. Interesting that they are not all showing in Softaculous. Can you share a screenshot of what you are seeing?
Thanks,
Ross
