I have recently upgraded web site from Sitecore 8.2 to 8.2 update 7. I have enabled the sitecore xDB in sitecore.xDB.config. Now when i am browsing the web site, i am getting the following error.
Could not get pipeline InitializeMongoDbCollectionIndexes(domain:)
I have already tried issue Cannot patch Sitecore initialize pipeline (Sitecore 8.1 Update 3) but it does solve in my case.
