Beta version 1.2.23 resolved the issue for me!
Screen shows the following text when I click “next” when trying to go to the scan step and create a package
Fatal error: Call to undefined function sanitize_textarea_field() in /home/oakhillm/public_html/wp-content/plugins/duplicator/classes/package/class.pack.php on line 322
I am experiencing this exact same issue. I’ve used Duplicator many times in the past and this is the first I’ve seen this.
WordPress 4.5.9
Duplicator Version 1.2.22
