This is on version 1.8. I logged in as author on another web browser to check the back end functionality. Everything was as expected but the Slider tab in the admin control panel is still live.
Authors have the ability to add and delete slider items. I assume this is a bug. :D
However, if it is not, what would be the procedure to delete the Slider tab after the site is configured? I think some PHP just needs to be commented out somewhere?
