I'm upgrading from Sitecore 8.1 rev3 to Sitecore 9.1.
The error is pretty straightforward, however I have already made sure that the 9.1 version of
Sitecore.Analytics.dll - the DLL that contains
Sitecore.Analytics.Pipelines.Initialize.ShowXdbInfo - is both correctly referenced by my project and present in the
My hypothesis is that something in my 8.1
config is breaking the system and triggering a deceptive and misleading error message, but I'm not sure what I could do to narrow it down - perhaps replace my entire configuration with the 9.1 default and gradually replace it with mine until I find the culprit?
I hope it won't have to come down to this.
Given the context, why I am still getting this error?
