This has also caused issues on two of my client sites. The URL paths being generated for the “Browser Cache” option are incorrect. Disabling Browser Cache fixes the immediate issue.
Custom functions run after a redirect.
The form would submit on page1, redirect to page2, which then run php code based off of the submitted values on page1. The code works perfectly on version 2.9.33, but exhibits the bug in version 2.9.36.
I also submitted this to Ninja Forms support, but this is a more public forum and I imagine others have the same issue.
Thank you for your help!
