Steps to recreate:
1. Create a new custom Field Group
2. Add the default text box (use default settings)
3. Click Publish
4. I get the error
This was working earlier today in my remote dev environment. I cannot reproduce the error in my local dev environment. Plugins are all up-to-date.
The trace directs me to a function that seems to process tabs, so I disabled the tabs extensions. I still get the error.
I don't know what else to try at this point. Anyone have any ideas?
