  • Hi,

    Have you just update to Sitecore 8.1? Can you provide the configuration file of the Sitecore.ContentSearch.config found in the App_Config\Include folder

    This issue is mainly due to corrupted config file in your Include folder. You can copy all the configuration files from another Sitecore 8.1 instance where the publishing is working and paste them in the Include Folder.

    Moreover, if you are using Mongo DB, please check the configuration and connection string and also, if it is running.

    I just wanted to add one line here, if replacing app_config files doesn't work please replace your bin folder too.

    We are also having same issue and replacing app_config doesn't help, after replacing bin folder it started working.

    Thanks nice catch, I got bin replace idea by this post!!!

    Brilliant, It was that Mongo wasn't running for me.
  • For me, this same exception was caused by invalid credentials for Coveo, our Search implementation.
    I had restored my dev env from prod, and forgot to reset the Coveo for Sitecore user+pwd.

    In my case the issue was that certain items were not published to one of the publication targets so the on publish end event failed due to not being able to find the items. Publishing the missing items before retrying the package install solved this. The logs are your friend for figuring this stuff out.
