Hi, I'm using Revive 3.2.1, but I cannot select asynchronous tags for my zone. Zone type is Banner, Button or Rectangle, and I've tried different sizes. My update page says: You are currently using Revive Adserver v3.2.1 running on Apache 2.2.22, PHP 5.3.10-1ubuntu3.19 and MySQL 5.5.29-0ubuntu0.12.04.1. Any ideas?
