Visiting the site gives this error. jtablesession::Store Failed DB function failed with error number 1226 User 'highcharts' has exceeded the 'max_updates' resource (current value: 36000) SQL=INSERT INTO `jos_session` ( `session_id`,`time`,`username`,`gid`,`guest`,`client_id` ) VALUES ( '8cre30vqdh3ip8hh0iebn7buq5','1361463112','','0','1','0' ) Googling jos_session reveals the site is built using Joomla.. Should probably consider doing something about this.
