Blogger post footer elements cannot be rearrange, move or toggle the visibility
Some how my Blogger post footer elements cannot be rearrange, move or even toggle the visibility from the "Blog" widget settings located in the Blogger page elements. I guess this is what happens when you tinker your Blogger template too much and too many times. This is how i manage to fix it.
Use "Revert Widget Templates to default" for the "Blog" widget.
Note: After you have revert the widget to default, any previous customization done within the widget code will be lost.
