run this command in sql:
CREATE TABLE IF NOT EXISTS smf_ads (
ADS_ID mediumint(8) unsigned NOT NULL auto_increment,
NAME tinytext NOT NULL,
CONTENT text NOT NULL,
BOARDS tinytext,
POSTS tinytext,
HITS mediumint(8) NOT NULL default '0',
TYPE smallint(4) NOT NULL default '0',
show_index smallint(4) NOT NULL default '0',
show_board smallint(4) NOT NULL default '0',
show_threadindex smallint(4) NOT NULL default '0',
show_thread smallint(4) NOT NULL default '0',
show_bottom smallint(4) NOT NULL default '0',
show_welcome smallint(4) NOT NULL default '0',
show_topofpage smallint(4) NOT NULL default '0',
show_towerright smallint(4) NOT NULL default '0',
show_towerleft smallint(4) NOT NULL default '0',
PRIMARY KEY (ADS_ID)
);
