Could it be because there are no articles under "General Articles" ?

Could it be because there are no articles under "General Articles" ?

No don't think so Les, I have articles in my General Category.  I can only replicate the error if I ad a sub cat to General articles.  Regardless of whether they have anything in them it seems to throw the error.

I noticed if I append my site url with ?cat=2 the page that comes up only shows a button with "Portal Features" on it, clicking this results in that error.

[Lesmond]

I have removed the "Portal Features" category but I am not sure if the error appeared before doing that.

I would leave as is for the moment Les, see if @rjen or Tino can come up with a fix for it, hopefully they can also replicate it.

One thing also noticed, but unrelated.  While trying to replicate this I deleted the sub cat name and saved, there was no way to get back to that category to edit it afterwards, even though it's obviously still there. So that's another issue.  Probably needs some sort of default value.

That's the default Cat list setting. The page is empty because it does not contain any articles...

I can see the error: it comes up when there is a subcategory created...

[@rjen]

Go to the category settings, switch ON the setting show subcategories and save it. Errors will be gone.
It seems the variable is not set on install...

Thanks @rjen, yep switched on "Display any child categories?" and indeed the errors stopped.
