I have created a new site collection of type community site on my development machine, then I have backup the site collection and I restore it inside staging server.

I am lo-gin as the site collection administrator on the staging environment and I am able to add new discussion , new category. but if I try to click on the discussion to read it or to reply to it I will get the following error:-


And the URL generated will look as follow:-


Can anyone advice what might be causing this??, baring in mind that the discussion forum is working well on development machine. the problem is occurring on the staging environment , where I have restore the backup site collection.

Thanks in advance for any help.

  • I am having the same issue. Check the site pages, does the 'topic.aspx' page still exist. In my case it was not there, and it was not in the recycle bin. I have restored it from another site collection. This fixed the error 404, but for the discussions does not load. I am still trying to fix this. Sep 3, 2015 at 14:15

If you have an updated backup file of your SharePoint database then manual method is for you. Simply restore it and make your database error/corruption free.
