    Hello, this is really a pain. I uninstalled and reinstalled the plugin, but this is happening still.

    I believe spammers call plugins/sabre/sabre_captcha.php?sabre_id=xxx directly. The error can be provoked by calling the plugin with a too short sabre_id. Can this be made saver (using referer, checking that the id is correct)?
