Panaghioti, Glory be to God, thanks for insisting. I HAD read your explanation, but did not understand then that by adding all these, they would appear as the way I had already configured; for instance, if I add the widget Categories, that all my categories would be there. I thought it would be like restarting from scratch, but I tried with one, and it did work!
As you mention in your post that beginners are taken aback, yes I sure was, maybe it might be good to specify that the widgets they will add will show as the way they had populated them, or whatever the technical word is.
So thanks a million, and I will now work on inserting my pictures.
God bless you.
