A custom Toolset form used with Elementor stopped working on the live site. The page showed a blank screen, the admin bar was missing, and editing or creating forms triggered critical errors. Server logs pointed to malformed conditional settings inside the form.
Solution:
The issue was traced to broken or malformed form conditionals. The recommendation was to recreate the form from scratch and make sure the conditional logic is added correctly, instead of trying to repair the damaged form configuration.
