   captcha-options/string-length is set to "7". In my servers error-log I am getting these:

   [PHP Notice: Uninitialized string offset: 0 in /xxx/wp-content/plugins/sabre/sabre_captcha.php on line 91

   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)?
