Changing icon of banned user
 

I found out that the icon of a banned user is the same icon as the icon for a errormesage.
Now I would like to change the icon for a banned user (yellow triangle) into red.

However, I can't find the script where it is set.

But where to change it???

There is no icon for a banned user so I am unsure of what you are talking about exactly. Can you post a link to see this banned user so we can see where this icon appears?

Ah, ok...

Then it must be in the plugin "Members who have visited today".

I think the best thing to do is ask Paul where to change it.

P.S.
It shows not only in "Members who have visit today", but also in "Who's online". (second screenshot)
