here's my first attempt to fix that problem. as i said you need to add a column to your xredirect_statistics table, you can do that by executing the following line on your database:
Code:
ALTER TABLE `xredirect_statistics` ADD `target_server_id` INT( 11 ) NULL ;
please try it and tell me whether it fixes your problem. i haven't tested it myself yet but will do that now. if it seems fine to me i will release it as RC2, unless you answer and still report problems.
