Sorry, yes, that were I was/am. Not working. I did recently upgrade to EasyApache 4 and switched PHP version to 7.0. It worked before I did so. Not sure if that helps.
Also, I am able to get the tab in place, but when I assign a node to the tab it doesn't work. Also worth noting, I am unable to assign any node to any of the stock navigation positions (tabs), e.g. Home, forums, etc.
