Instalar o mod e configurar na admin, o que não consegues fazer?
http://custom.simplemachines.org/mods/index.php?mod=1936Espero que tenhas lido isto:
Please note:There is yet another bug in the install script that causes db_create_table to fail and continue installation. When installation is complete, please run this code in phpMyAdmin or wait for the next patch.
CREATE TABLE `{db_prefix}forums` (
`forum_name` VARCHAR( 255 ) NOT NULL ,
`cat_list` VARCHAR( 255 ) NOT NULL
);
INSERT INTO {db_prefix}forums (forum_name, cat_list) VALUES ("one", "1");
Remember to replace {db_prefix} with whatever your database prefix is.
