Hello, I will use "message" template for serving ads inside "signature" block. Every 5th. post I will add adserver code. when users reply threads with quickreplay, AJAX returns whole message template included signature block. I think, because of my adserver's code when users reply after 4th post with quickreply form , page goes white blank page. Actually message is being sent. When I remove adservercode it works normal. Or while just browsing pages, pages and ads are seen normal. So, I am looking for a variable to use and check in "message" template, to find out if used quickreplay If "message" template called by quickreplay , I will not show signature. Do you know any variable to control in "message" template if it is called by quickreplay ?
