Engage the switch next to a category to allow it. If you leave the switch off, the category will not be allowed for that account.
Here are some examples of categories (groups) that users might not be familiar with:
•Miscellaneous – Usually private (local) IP addresses such as intranet, 127.0.0.0/8, 192.168.0.0/16, etc. When you get a 403 or 404 error code, the website will also match this category.
•Not resolved – This category includes web pages that are not resolved because of an error when connecting to the Parental control database engine.
•Not categorized – Unknown web pages that are not yet in the Parental control database.
