 * You have a bug with Ninja Forms integration (latest versions at the date of creting
   this topic).
   As soon as I disable the plugin, NF form edit screen works fine.
   When is enabled I get an error related to backbone/fieldset
 * As a temporary fix I’ve turned of require __DIR__ . ‘/ninja-forms/bootstrap.php’;
   as I dont need it but created this support forum so you are aware.

 * Hey [@vbmv](https://wordpress.org/support/users/vbmv/),
 * I installed the latest version of NF to test and was not able to replicate the
   issue. Can you please share which version of our plugin you are using? 
   Also,
   if you disable all plugins except ours and Ninja forms, do you still see the 
   error?

 * Hi Harish,
 * I’m Faisal from Ninja Forms. I was able to replicate the issue on a fresh installation
   with only the **Ninja Forms** and “**MC4WP: Mailchimp for WordPress**” plugins
   activated, both on their latest versions. Please have a look at the screen recording
   below.

 * Hey guys,
 * I was able to reproduce the issue, it seems to only occur when not connected 
   to Mailchimp or somehow no audiences in the connected Mailchimp account. Will
   be fixed in the next plugin release!
 * Sorry for the hiccup, but thanks for bringing it to our attention.
 * 
   Best,Danny
