I just happened to see that Thread and some Posts regarding the problem, that the extra navbar doesn't appear in all sections (PhotoPlog, vBAdvanced, Arcade...). My Code is different than yours but I still use the same Plugins. What you have to do is as follows...
Create an new Plugin with the Hook "global_start" and its Code as below...
HTML Code:
<plugin active="1" executionorder="5">
<title>navbar2 plugin part #2</title>
<hookname>global_start</hookname>
<phpcode><![CDATA[$insert = '$navbar2';
// Insert above Info into Template 'navbar'
$vbulletin->templatecache['navbar'] = str_replace($insert,$insert.fetch_template('navbar2'),$vbulletin->templatecache['navbar']);]]></phpcode>
</plugin>
After you should remove the Plugin with the Hook "parse_templates" because it doesn't need anymore. Now it works in all sections
