Does someone get this soft reject

  1. Custom widget areas must use the safety condition “is_active_sidebar” to ensure no naming conflict with other plugins.

Any of earlier 7 reviewers do not say nothing about this.

And second:

  1. - do not look at .ds_store files, their have been delete. But I’m 100% that every theme in here using iframe have that errors without install Themeforest check plugin, because wp_oembed_get generate iframe
  1. Yes, it’s a common soft-rejection reason and it’s been around for quite some time. It’s a standard WordPress requirement, not envato-specific.
