Thread:Project:Support desk/How to hide "View History" button for unlogged users?/reply (9)

It is possible, but not out of the box. ;-)

You can do that in your skin files. If you use the Vector skin, then you can do that in skins/Vector.php. Somewhere in the head of your page, add some lines of PHP code, which check, if a user is logged in currently and if not, then include a CSS file with these few lines we gave you (which hide the button).

(I have not tested the above; but it should give you an idea, of what you should be able to do. :-) )
