<div class="input-form-td-break">How to edit settings for HTML Purifier module</div>
<p>
A <tt>config.php</tt> file exists in your <tt>mods/htmlpurifier/</tt>
directory. This file contains your custom configuration: in order to
change it, please navigate to that file and edit it accordingly.
You can also set <code>$GLOBALS['PHORUM']['mod_htmlpurifier']['wysiwyg']</code>
or <code>$GLOBALS['PHORUM']['mod_htmlpurifier']['suppress_message']</code>
</p>
<p>
To use the web interface, delete <tt>config.php</tt> (or rename it to
<tt>config.php.bak</tt>).
</p>
<p>
<strong>Warning: Changing HTML Purifier's configuration will invalidate
the cache. Expect to see a flurry of database activity after you change
any of these settings.</strong>
