 * Hi there,
 * I’ve not been able to reproduce this issue on my testing site, so the first thing
   we need to do is check if this is a bug.
 * Will you check if you have the same issue under these conditions?
    * all other
   plugins deactivated * any custom code removed * WP 2017 theme active * running
   the current version of Formidable * running the current version of WordPress *
   all site, server, and browser caches cleared * PHP version of 5.6.20 or above*
   Cloudflare or any similar service set to development mode<
 * You can find more detail on how to find a conflict in the docs: [https://formidableforms.com/knowledgebase/what-plugins-are-known-to-cause-conflicts/#kb-how-to-find-a-conflict](https://formidableforms.com/knowledgebase/what-plugins-are-known-to-cause-conflicts/#kb-how-to-find-a-conflict)

 * Hi [@njones35](https://wordpress.org/support/users/njones35/),
 * I checked all the things from above.
 * Also, I have Formidable Forms 4.03.02 and Formidable Forms Pro 3.04.02.
 *     ```
       function isGoingToPrevPage( $object ) {
       		return ( typeof frmProForm !== undefined && frmProForm.goingToPreviousPage( $object ) );
       	}
       ```
   
 * It seems frmProForm is never declared and cast it to a string seems to fix the
   issue.

 * Thanks for that.
 * I’ve reported this to our developers.
 * It seems to affect Formidable Lite, but the problem seems to disappear when Pro
   is activated. If you are a Pro user could you confirm this on your site?

 * I have Pro plugin enabled (but I do not enter the license key yet) and the problem
   still persist.
