I recently upgraded a 2.5 Joomla installation to the latest Joomla 3. Everything went pretty well but one error exists that I cannot solve: All the articles show a small gear in the top right corner but clicking this button does not do anything.
The funny thing is when you log in: The button is working as it should and the dropdown menu is shown with options to print/share/edit.
This is the button I mean: https://i.stack.imgur.com/PcgCw.png
Does somebody know what is going on?
