its strange but ,color codes show in peoples usernames on forums..for example
style="color: ##FF000">J-English.
The color works when viewing forum boards,you can see red as administrator..blue as members etc...but within when reading a post you can see peoples color codes in there usernames above there avator.
That definitely sounds like a problem with your custom theme. I would recommend making sure that you're running the latest version and that it is compatible with your forum version. If it still doesn't work, you might have to try a different one.
just found a solution on phpb3 i hate to find "view_topic_html and replace this <b class="postauthor" x with this <b class="postauthor" < and it worked!.
