Starting with 1.30 theme version was added option to manage submit form fields and mandatory fields. Help: https://help.wprentals.org/article/1-30-how-to-manage-submit-form-fields-and-mandatory-fields/

When you submit a listing there are some required fields in the “description” section that are mandatory. If those fields are not filled in with data the continue button is not getting active.

To disable the “mandatory fields” you need to go into ajaxcalls_add.js and at line 288 you have the function submit_change(). In this functions there are the “checks ” you may need to delete.

Same thing happens if you want to add new new required fields. Add the new checks in this function.
