 * Hello, in a multisite installation this plugin shows the following errors when
   activation in each subsite:
 * Notice: Undefined variable message_controller in …/plugins/happyforms/inc/classes/
   class-migrations.php on line 119
 * Notice: Trying to get property ‘post_type’ of non-object in …/plugins/happyforms/
   inc/classes/class-migrations.php on line 119
 * And no sample form is added.

 * It seems you’ve spotted an ugly bug, sorry for that! We’ve just patched it and
   a new release is on its way. Would you update as soon as it is available, and

 * Hello!
 * I deleted it, and in reinstallation of the new version it looks it is solved.
   But there is not initial sample form.
 * Thank you!

 * Hello again,
 * When editing the form and save, it dissapears of the preview with the message
   Page not found.
 * The shortcode works, but not the preview…

 * Hey again, [@promostudio](https://wordpress.org/support/users/promostudio/)!
 * Does this only happen after saving your form for the first time? Can you see 
   the same error when opening the form edit screen again from **HappyForms** → **
   All Forms** table?
 * Could you pleae try deactivating all plugins (except HappyForms) and see if it
   helps? Does resaving **Settings** → **Permalinks** screen without making any 
   changes help at all?
 * Let us know your discoveries! 🙂
