I had a working Chronoforms 5 form that I just changed a few dates and suddenly stopped working. I tried debugging the form; however, the form wasn’t submitting to the next page for the debugger to even show me the variables. I found my answer here.
In the Form go the “Set up” tab. In the “on load” section you will have a “HTML (Render Form)” action. Edit this and toward the bottom you will see “Relative URL“, set this to “No“. It has something to do with SEO options.
I hope this helps someone else out there….
