Catagories in meta data - no comma?

I am very new to Zen Cart, however I was viewing the source to my home page, and noticed that in the meta key words section it has the catagories names in. This is something that I thought would be helpful, however there is on "," between the names. This is what I get:
<meta name="keywords" content="Adhesives Embellishments Flower Soft Paper....

I don't know much about how meta data is read (im still learning) however I am sure that it is supposed to read <meta name="keywords" content="Adhesives, Embellishments, Flower Soft Paper, ..... etc etc

If someone could tell me what has gone wrong, and where to look in fixing this, I will be very grateful. I did do some digging around here, but there is so many different questions RE meta data I just can't find it.

Thanks.

If you prefer to have the automated list of keywords separated by a comma instead of a space, simply change the setting in your /includes/languages/english/YOURTEMPLATE/meta_tags.php file:```
// Define divider ... usually just a space or a comma plus a space
define('METATAGS_DIVIDER', ' ');

I double checked this, and It is already set like this. however I still have no comma between the key words.

Ahem :blink: ... I meant to CHANGE it to put a comma in if you WANT a comma ... like this:

// Define divider ... usually just a space or a comma plus a space
  define('METATAGS_DIVIDER', '[B],[/B] ');

Oh,
Thanks for this. It worked. I really appreciate it.
