After upgrading to the interim release, the iTrader acts like it's turned off, even though the permissions have been correctly set and the hack is active.

Well, if indeed iTrader is set to "open" in your vB Options, then there is probably a version mismatch somewhere. In the new release I've coded it to be a bit more explicit if there is a file vs DB difference, but with this (and previous releases) it just says closed to prevent any issues. I'm assuming you chose the overwite option when you updated? Make sure you are using all the latest files.

Last thing to check would be to enable debug mode on your forum (probably best to close the forum temporarily). Go to your vBulletin Options -> Version Info and Other Untouchables. Then look for iTrader Version Number, it *should* be 2.1.0, if it's not then click the 'edit' link and under the "Default" field change it to 2.1.0 and make sure the Data Validation Type is set to "Free".

If none of that works, let me know, but one of those has to be the problem.

Is it possible to disable negative and normal feedback ratings?

Easiest way without modifying the code would be to just remove those options in the template where they input a rating.
