Hardly worth a ticket, but for validation nuts:
There's a typo in the file frontend.php of the plugin, on line 88 it refers to tyle instead of type - here's lines 87, 88 and 89 of the code:
echo "\n".'
<style tyle="text/css">
.clplinkcategory { ';
Here's the correction:
echo "\n".'
<style type="text/css">
.clplinkcategory { ';
That's all...
