[Plugin: Job Manager] category pages?

Perhaps I am an idiot but I swear I thought this worked before without me doing anything.

Everything works brilliantly except when I click on the related categories (such as “feature-film” or “other”) I get a “Not Found” error. Now like I said I swear this worked before but perhaps I’m just crazy…

I thought maybe we needed to put shortcodes on each page so I made one of the pages as a test but can’t locate any shortcodes to put there and with the blank page nothing seems to happen.

Can you tell me what I’m doing wrong?

Thanks and best wishes,
Kristen
