I installed k2 and the additional categories for k2 so that I could post k2 articles to multiple categrories to display on my website. I seem to have lost the ability to sort articles in the process. I can see the sort option for modules and other areas but not for k2 content. Which settings should I change to restore this functionality. I have tried disabling and enabling the additional category plugin. Any help would be appreciated, I am trying to get a website running for my students to use in Korea in lieu of classes because of the Corona epidemic.
