Wordpress Affiliate banner problems, not showing
 

I have a problem with affiliate banners not showing in wordpress, recently i added one to a text widget in wordpress and that one displays fine, i add a second one to that widget and underneath the first but it wont display, either in firefox or IE.

I also hardcoded one into the footer and that wont show in firefox or IE.

Have you had problems with affiliate banners now showing?

A few times i thought i had fixed it as i altered things and then it displays, then i check again and nothing.
