Hello,

 

I've installed EPiServer 7.5 CMO using Deployment Center on EPiServer CMS 7.5. Clicking Add campaign or Add test buttons in CMO interface, I'm getting the following error: "Object reference not set to an instance of an object."

 

[NullReferenceException: Object reference not set to an instance of an object.]

In web.config viewstate=true (I found same issue in Epi forum)

 

 

I would greatly appreciate your help.

Have you tried to install CMO on an existing site?

We have seen cases where doing a reinstall gets the user around this error.

Which CMS 7.5 version are you using? Right-click EPiServer.dll in the bin folder of the site and in Properties check the file and product version in the Details tab.

I couldn't reproduce this issue with the latest CMS7.5 patch and CMO7.5 http://world.episerver.com/Releases/EPiServer-75--update-28/
Have you updated CMO to the latest version via NuGet?
