I haven't been able to add smilies to any posts on our site. Checking the admin area, the custom smilies I had were all missing their links (I have them uploaded here at our website). So I went through them all and re-added the links. But they are still not working. And looks like it's not just the custom smilies but even the default ones used here. When I add a smiley, only the word "undefined" shows up.
Looks like the default smilies work here in the support forums. I just can't add them to our forums.
