This error happens during runtime, right and not "install time"?
Install episerver community in cms version9.0,then the error happens in install time and install community in cms version 7.15 error occurred in runtime.
Try installing the package via Nuget Console and add this command (-IgnoreDependencies) to see if that helps you.
I try to install episerver community in cms version9.0 using episerver visual studio extension then it shows "Already referencing a newer version of 'EPiServer.Framework'".How to solve this problem?
I installed episerver community in cms version7.15 it shows error "Object reference not set to an instance of an object".I check the error log:
Does any one know this?
Thanks in advance
