Try running the above query from your adminCP. Or, run it through phpmyadmin, without using the table prefix in front of the name, in other words, run it like this:
Code:
CREATE TABLE `warn_notes` (
`wid` int(15) NOT NULL auto_increment,
`warned_user` int(15) NOT NULL default '0',
`warned_by` int(15) NOT NULL default '0',
`warned_time` int(15) NOT NULL default '0',
`warned_note` text NOT NULL,
`warned_post` int(15) NOT NULL default '0',
`warned_type` smallint NOT NULL default '1',
PRIMARY KEY (`wid`)
I just noticed you had upgrade from ZT's hack, that's why it didn't add that table for you, I haven't updated that script to the latest release.
