How do I disable the popup? There are no option to do that... according to the documentation you should have that option, but you don't.
And would be nice to have a 2017 title too

Have Joomla 3.8.2

I was about to ask this question too, as I love the themed frame at the bottom, the snow but have no use for the big red popup and possibly the smaller one to the right bottom.

Be interested to hear supports guidance on this but could we not use the css of

display: none;

I have just tried with the bottom right side small banner and it's worked with this css;

/** SJ Xmas Small Banner **/

.sj-xmas .banner-1.open-xmas, .sj-xmas .banner-2.open-xmas {
display: none;
}

Just place the above css in your templates custom css file if you have one within your templates file (most people do nowadays)

Hope the above helps.
