I have some custom filters which depend on campaign name (pk_campagin). After upgrading to Piwik 3.0, these filters don’t work anymore. I’m using self hosted community edition.
I am receiving a “The segment ‘campaignName%3D%3Dchat’ is not valid.” error. Also, I cannot select campaign name, keyword and the other options anymore to create a filter.
What is going wrong here and how to fix that problem?
