[Plugin: Flexi Quote Rotator] Quote Rotator not loading on non-root URL pages

The $quoteRotator object does not seem to be working on pages within a “sub-folder”, such as
http://www.example.com/some-category/my-article

but it is working on all pages that are in the root path, such as
http://www.example.com/my-page

I am outputting the quote rotator using the php snippet in my template file.
<?php if($quoteRotator) echo $quoteRotator->getQuoteCode(); ?>

Wondering if anyone has experienced this, or knows how I might correct it?

Thank you!
