Here's the relevant portion of my template.html:
<BODY>
<!--
Url: -URL-
Reason: -REASONGIVEN-
Reasonlogged: -REASONLOGGED-
User: -USER-
IP: -IP-
Filtergroup: -FILTERGROUP-
Category: -CATEGORIES-
Byp: -BYP-
-->
<br>
<br>
<CENTER>
<table cellpadding="20" bgcolor="#efefef">
<tr>
<td align="center">
<H1>Access has been denied!</H1>
Access to the page:
<P>
<strong><a href="-URL-">-URL-</a></strong>
<P> ... has been denied for the following reason: <P>
<strong><font color="#000000">-CATEGORIES-</font></strong>
<br>
<br>
You are seeing this error because what you attempted to access appears to contain,<br>
or is labeled as containing, material that has been deemed inappropriate.<br>
<p>
If you have any questions contact someone in IT.
</p>
</td>
</tr>
</table>
Then in order for the -CATEGORIES- to work, you have to manually edit your /etc/dansguardian/blacklists/(category)/domains list and add to the very top:
#listcategory: "Streaming TV" (or whatever you want it to say)
You'll have to do that to each category domain list you have blocked. Otherwise it will say N/A.
Hope that helps!
