Installed to 3.6.7 PL1.
Initially, I received this error:

The following dependencies were not met:
This product is not compatible with version 3.6.7 of vBulletin. (Compatible starting with 3.6.4 / Incompatible with 3.6.6 and greater)

In the XML file I replaced maxversion="3.6.6" with maxversion="3.6.8" as suggested in a previous post.
After the successful import I found the plugin disabled by default (you can see a line through the title in the plugin manager) so I enabled it.

In vBulletin Options > Help BB MicroStats I enabled the plugin and turned on all the options. Debug Mode status only displays if it is enabled in the /includes/config.php file.

The template modification as supplied in the readme.html file corrupts the display so I wrapped it in it's own table tags.

<table cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="$stylevar[outertablewidth]" class="page" align="center">
<tr>
<if condition="$show['microstats']"><!-- {microstats} --></if>
</tr>
</table>

Then I placed the code below the first table in the footer template. Hack working as expected. These stats are for forum home when logged in.

I've elected not to display Active Users, Memory Usage, and GZIP Level.

I am also running vBSEO without any conflicts.

Explain is also working fine.
