[Bad redirect on destination URL in newsletter banner]

@mrmartin It happens that I was trying to deliver two campaigns for a single email zone at the same time. So the ad server couldn't tell which link to address to the banner that was served. If you only deliver one campaign/banner at a time the problem will be solved. 

[Bad redirect on destination URL in newsletter banner]

Problem:
After click on the newsletter banner it doesn't redirect me to the destination URL defined on banner configurations in the ad server. The browser open the url placed in the "href" param of zone tag/code ("http://adserver.guitadigital.com/www/delivery/ck.php?zoneid=2")

Here's the code placed on my newsletter html:

<!--/*`
  *
  * Revive Adserver No Cookie Image Tag
  * - Generated with Revive Adserver v4.0.0
  *
  */-->

<!--/*

  * to

  *
  */-->
