I am guessing that the 'add a file' button at the foot of each article should be hidden from users who do not have permissions to use it. Unfortunately at present, the button - a right pointing arrow - is visible to everyone.

People naturally think it leads to the next article, but of course they get a 'forbidden' error message when they click on it.

I have searched through the templates but cannot pin down how to hide it (from everyone if necessary).

Any help would be appreciated.
