The Admin activity log is for review purposes if there was a problem ...
So you are safe to remake it ...
Go to phpMyAdmin and use this to drop and re-create the empty table to eliminate this error ...
You appear to be missing the auto_increment ...PHP Code:DROP TABLE IF EXISTS admin_activity_log;
CREATE TABLE admin_activity_log (
log_id int(15) NOT NULL auto_increment,
access_date datetime NOT NULL default '0001-01-01 00:00:00',
admin_id int(11) NOT NULL default '0',
page_accessed varchar(80) NOT NULL default '',
page_parameters text,
ip_address varchar(15) NOT NULL default '',
PRIMARY KEY (log_id),
KEY idx_page_accessed_zen (page_accessed),
KEY idx_access_date_zen (access_date),
KEY idx_ip_zen (ip_address)
) TYPE=MyISAM;
