Hi Hello, I'm new to the forum! I'm using revive adserver to deliver ads to a phpbb forum I have been using older versions of the software for many years with various versions of phpbb I recently had my banners running on a phpbb 3.1.5 forum, no problems, I used and extension to insert them into the templates I moved to 3.1.8 and the extension I was using no longer works, so I created my own events, but couldn't get banners to be displayed I used an old version of 3.1.8 to enable the use of the custom code extension I was using and now cannot get them to appear has anybody got any experience of using invocation code in the latest version of phpbb 3.1.* many thanks Tony
