I just installed the latest version onto my Ubuntu 16.04 server. Everything seems to be working fine and I can authenticate with my Unifi wireless system. However I'm having some issues in the admin dashboard. Mainly half the settings I try and save do not actually save. This is most prominent on the landing page configuration section. If I try and change anything here, it says in the corner popup that is has been saved, but when i refresh the page it is back to the defaults.
Additionally it only only allows me to edit the welcome page and not anything else, such as the login forms, etc. - If i try and click on anything in the preview window, it just goes to the 404 page. This is the same on pretty much any editor page, however most tables are still working, such as adding a guest user or a new admin - these all save into the database fine.
I have tried loading the page in Chrome, Firefox and Internet Explorer all to the same effect. I do seem to get a bit further in Internet Explorer but really not worth mentioning.
I also tried to create a template myself, and read through the documentation for Jinja2, however I can't find where any of the form fields are stored, so I can't apply a custom HTML to it as it seems that is dynamically loaded and the basic form css cant be changed. I think there is suppose to be a custom CSS field in the landing page section but again, I can't access any of this and it wouldn't save even if i could see it.
Any help would be much appreciated.
