Dody, I'm sure you knew where this damned comma was, and you did not want to tell us
So, I found it !
It was hidden in the lib/category.class.php file, on line 539.
The code was :
PHP Code:
$category .= "<a href=\"$sub_url\" style=\"$this->subcat_link_style\" id='cat_$sub_id'>$sub_name</a>, ";
and you have to modify it into :
PHP Code:
$category .= "<a href=\"$sub_url\" style=\"$this->subcat_link_style\" id='cat_$sub_id'>$sub_name</a> - ";
It's better to use "-" intead of "," when the name of the category is composed of many words. You'll say that you can write "nuts&bolts" intead of "nuts, bolts", but in the rest of the world, lots of people don't use the "&" so frequently.
