The "Ignore updates" feature supports two different modes:
This method will prevent an update notification when a page contains a certain pre-defined text. This feature can be used when a page regularly shows a certain error message, for example "Too many users online, please try again later" or "Could not connect to database".
This method only allows an update notification when a page contains a certain pre-defined text. If this pre-defined (white listed) text is not found in the page, then WebSite-Watcher will not alert an update.
