Styles & Layouts stopped working with the Gravity Forms 2.5 release.
The page that appears within Styles & Layouts where you style your form is now a blank page whereas previously it showcased all fields and corresponding styling.
There have been a few recent interim releases. Can you check that you’re running the latest stable interim build of Gravity Forms 188.8.131.52, available from the downloads page? Some of those releases introduced fixes that may have affected form rendering in the Customizer.
Reference: How to Manually Update
Updated to 184.108.40.206 and Styles & Layouts still not working.
Hi Sinisa. Thank you for the report. Can you please report that to the authors of the Styles & Layouts plugin as well? Thank you.
