thanks for the reply Reycer sorry didnt realise i left out the most important bit
basically the iframe we had was when posting a new post we had the option to enter a url in a iframe with the bb code [iframe] and the persons post would then be a post with the web page in it rather then just a url
this is an example from my forum if you see the original post it works as it was posted before the upgrade but if you see the last post on the thread by myself it just becomes a broken url
