Hi guys... thought you'd wanna know about this one. While studying the Magnum Opus index.php file, I noticed that the call to the script for the clearfix refers to a file in the 'Business look' template folder, which will obviously only work if the site also has the Business Look template installed.
from Magnum Opus' index.php file, line 1785:
<?php if (($s5_clr_fix == "enabled")) { ?>
<script type="text/javascript" src="templates/businesslook/js/s5_clr_fix.js"></script>
<?php } ?>
I assume this is just a cut-n-paste error, and thought you should know.
Cheers!
