hi.
ive solved this problem by removal all records in sql table ‘wp_terms’ and updating ‘terms’ from the blog admin menu ( after updating the in table ‘wp_terms’ ‘slug’ should be readable from phpmyadmin, navicat or any other program for work with mysql )
btw, before that solution i havent terms in my blog, its surcefully adding but not displayed. now all seems ok
hope it will help
