Hi there,
It is under Appearance → Customize → Content → List Views.
Thanks for your answer, Appearance → Customize → Content → List Views. and then Tiles: columns (Maximum) or jQuery Masonry: columns (Maximum) but that doesn’t work, do I have to set something else?
If you have the Left or Right sidebars enabled, it may automatically decrease to two or three columns regardless of the selected number, be it four or five. It is to ensure the content is not too much squeezed and titles and everything else is legible. It also does that on small screen devices such as tablets, and also with the Narrow layout, there would be only one column always.
Thank you very much for your response, I do have a left and right sidebar so the theme only gives 2 columns, now it is completely clear to me, thanks again and merry Christmas.
Awesome! Thanks, to you too!
