Hi, I am trying to install sourcebans, so far so good but I get kind of this errors when trying do something (add admin, add/remove ban etc)

(Cannot add or update a child row: a foreign key constraint fails (`amr_sbans`.`sb_actions`, CONSTRAINT `action_server` FOREIGN KEY (`server_id`) REFERENCES `sb_servers` (`id`) ON DELETE CASCADE))

Failed to insert the ID ban into the database: Cannot add or update a child row: a foreign key constraint fails (`amr_sbans`.`sb_bans`, CONSTRAINT `ban_server` FOREIGN KEY (`server_id`) REFERENCES `sb_servers` (`id`) ON DELETE SET NULL)

Database setting are OK,
Plugins works well,
Web panel works well,

How can I solve this error?

Edit:
Converting database from InnoDB to MyISAM solved the problem for me, thanks.
