Messaging Module

You are not authorized to post a reply.

    Hi all,

    I have a very long-living DNN installation (started with 4.9.5), and due to regular updates is now on 9.7.2. I installed the Telerik Identifier Module to prepare for the next step - and found this assembly:

    • DotNetNuke.Modules.Messaging.dll

    As far as I can see, this belongs to the old Messaging module, which is not in use anymore (it was displaced by a module called "Message Center", but obviously not uninstalled). I cannot uninstall this leftover from the UI, as it is marked as a System Module. It does not appear on sites that started with other DNN versions (from 8.0.4, or another one that started with 5.4.4).

    My question now is: Is it safe to run the following query and then uninstall the module?

    UPDATE {databaseOwner}{objectQualifier}Packages
    SET IsSystemPackage = 0
    WHERE Name = 'Admin.Messaging'

    (Well, to be true, I am sure that this will work and is safe, but I just want to hear some opinions)

    Happy DNNing!

      Hi Michael,

      I ran into the same issue. I changed the Package in the database to set IsSystemPackage to 0 so I could uninstall it.

      However, this didn't remove the assembly (.dll), so I removed that manually anyway.

      Hope this helps...

        yes, this was working (I also had to remove the assembly manually). Same here: https://dnncommunity.org/...t/1480 (without the system flag, but the assembly had to be removed manually).

        Thank you!

        Happy DNNing!

          I'm upgrading an instance from 7.4.2 to 9.12.0 for a customer.
          After upgraded to the 9.12.0, I've uninstalled the Messaging module and the process has removed the dll automatically.
          Previously, I also had to modify the system package flag in the database to unlock the uninstall command.
