I am trying to use the Table Manager to rename a field in an attribute table. However, the Vector Toolbar in my install of QGIS 2.14.0-Essen 64-bit Windows shows a toolbar with no tools in it. The toolbar handle is visible, but not tools are included in it. See photo below.
Furthermore, when I go into the Customization menu to try and add options to appear in the Vector Toolbar, I see that there are no options to add. All the other toolbars have a plus next to them that give you the option to add or remove tools. The Vector Toolbar has no plus.
