I have just upgraded my site to DNN9 from DNN8 and altough there are a number of UI improvements the functionality of basic things such as editing modules no longer works. When using the 'pencil' icon to edit a module there is no option to view the html or even edit via the rich text editor. Also a number of settings pages have been removed, or renamed?

Where can the previously named 'Host Settings' be found?

Any help is appreciated
