I have set the OpenX server and I am trying to generate a test ad. I have followed the steps mention and added advertiser, campaign and banners. I have also added a website, a Zone and added the banners to the zone.
Now when I am trying to generate the Invocation Code, the dropdown for selecting the type of invocation in coming empty. I have searched and could not find the answer. Can any one tell what might be wrong here? Thanks for your time. Below is the screen shot for the Invocation Code screen.
This should help you out. Your plugins aren't being read as installed.
They are located in [openX path]/etc/plugins/openX/openXInvocationTags.zip. Here is how to install them:
[openX path]/etc/plugins/
http://yourserver.com/etc/plugins/openXInvocationTags.zip
Here you go!
