Go to: ACP > Templates > Index Templates > index_whosonline_memberbit > and add the following code before every thing;
{$comma}
the code exist already!!
EDIT: it seems that the commas are not appear with the Greek Lang.... but I need to use it... anything I can do about it???
You'll need to add $l['comma'] = ", "; to the end of the global.lang.php file for your language, but if this isn't in there already, it's not a 1.6 compatible language pack, so you'll probably find other text is missing too.
yes... that's true! I fixed it!! thank you!
