hi, i have a problem during creation new category in ps 17, when i create a new category, appear this error message : "an error occured during creation category" then instead create a category with name it create a category with code.... 

then i have also active debug, and appear this error message :   ""×Duplicate entry '160-1' for key 'PRIMARY'   INSERT INTO `ps_category_shop` (`id_category`, `id_shop`) VALUES ('161', '1')

how i can solve this ?

thanks
