Cannot create Categories in Cassified Ads

Hello I have installed WP Adforest Theme and created all the around it, something is not working because I used to have 6 categories in the Classified Ads section, Now all the categories, tags, currency, condition, type, warranty fields are empty and even if I create new ones, when refreshing the browser these are all gone. Please your help.
