Commissioning all morning , A data table is missing , This is the developers deliberately ？
A data table is missing ims_mc_fans_tag_mapping,
Just add a table to the database
CREATE TABLE IF NOT EXISTS ims_mc_fans_tag_mapping (
id int(10) unsigned NOT NULL AUTO_INCREMENT,
uniacid int(10) unsigned NOT NULL,
acid int(10) unsigned NOT NULL,
groups varchar(10000) NOT NULL,
fanid INT( 10 ) UNSIGNED NOT NULL,
PRIMARY KEY (id),
KEY uniacid (uniacid)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
