During execution, there are situations when the captcha will be misunderstood, it will be occupied by a nickname, an incorrect answer to a secret question and other errors variations. You can set the number of attempts for registration, authorization, setting the value in the field: "Number of failed registration".
In case if there is an error during the runtime, xneolinks will retry. When attempts are exhausted, the resource will fall into the list of unsuccessful ones with the error "the number of attempts exceeded". In some cms, if comments are enabled, an attempt will be made to comment.
