2 column not working

I’ve had this plugin working fine on my site until just this weekend and with nothing other than a temporary server outage, I’m trying to figure out what may have interfered with the settings or prevented it from loading in 2 columns:

I’ve even tried a new shortcode:

[knowledge_base columns=”2″ alignment=”left” items=”10″ orderby=”title” order=”asc”]

this is what I’ve had on the page before that worked fine, but is no longer working:

[knowledge_base columns=”2″ alignment=”left” icons=”false” orderby=”title” order=”asc”]

page is https://www.qpractice.com/ncidq-glossary/

Can you see anything that may be preventing CSS from loading?
Thanks!
