I just uninstalled the Pro version and installed the free version instead. No more errors and everything is working fine. I am only using it for one Relationship field group, so the Pro version wasn’t needed. Thank you.
Nothing is being done to trigger the error. It just started displaying on the front end of the website this morning. This has all been working perfectly fine until now, so I am wondering if it is an incompatibility with wordpress core or one of the other plugins on the site.
Everything appears normal except for the glitch.
It’s a select field.
I’m an idiot. I mistyped the field name. 🙁
