You're in luck, I happen to have that mod installed on my test system...
Using Lynne's method - create a plugin using hook location style_fetch and use code
Code:
if ($styleid == 123)
{
$vbulletin->options['cybtopstats_enable_global'] = false;
}
but of course you want to replace 123 with the id of the style where you
don't want the stats to appear.
You might want to increase the value of "Execution Order" to something higher so that if any other plugin changes the style your code will go last.
