2 Column display not working

Hi all,

I’ve been using the momentous light theme on my site and activated the 2 column display on the home/archive pages.

I am unable to determine why, but for some reason posts are now shown only in the left column and the right column is left empty.

Is this an issue anybody has experience with? Any tips and suggestions are welcome.

If I need to provide more detailed information please let me know.

Tim
