XF 1.3 required field nat_popup_columns -- changing/creating nodes

[Kainzo]

Using 1.3.2 - not sure whats going on - it doesnt seem to stop me from changing or deleting/creating nodes - but thought it may be a bigger issue later.

That is an error from this addon:

This is probably a bad or incomplete installation of the addon. I suggest you simply reinstall the addon (reupload the files and reimport the XML).
