I was checking the theards but I can really find any solution of my problem.
The issue is during adding new ad, especially with categories. As I have few categories once I add new category ( test category in this case ) and adding the new ad 3 more fields appears like: STATE, Zip/Postal Code and TAGS - the attachement is the preview. In Classipress custom fields are this fields disabled.
Even when I try to add new categories the same problem appear.
