I've been working on a dev site for the past month or so. Everything was working fine. Started to upgrade the live site just now. It's pretty much all gone smoothly, except for 2 fields that are not showing on the site.
They are two P&T Checkbox custom fields. (Same channel). They are visible in the CP, and every entry has some options selected.
Now on the front end where I am displaying these options, nothing is output. It's the exact same template and set up that I am using in the dev site, which is working fine.
Not sure where to start trying or testing? Any ideas?
