I'm sorry, can you please tell me where that is? Or you refer to Article Manager > Options > Show Navigation ? Because that won't do it, it doesn't load even the titles..
Ok, so I accessed Menus > Main Menu > Name of the menu which is a Category Blog > Show Navigation. Also I checked Show navigation in Article options and in the specific article and they are both "Show", but it is still not appearing...
I installed a plugin to display titles and it works, it displays at the top of the content a link, it's here. But what I was interested in is creating in the left and right part of the theme the arrows to next and previous articles...In the template details there are no options for this, I just checked..
