You might have upgraded your Sharepoint to 2013, have this “Sorry, something went wrong error” and you don’t know whats causing it. This was my issues several week ago when I migrated our Sharepoint. I looked at the old version and it all works fine but on the new instance it does not work, I checked everything and compare with other sub sites still not luck. What’s even worse is that this error happened to two of my most simplest site on my Sharepoint, no customizations or custom solutions at all. What might be happening.
If it’s a sub site within a site collection that already had migrated successfully in the 15 hive then it would look like this.
But if it happens to a site collection which is still in the 14 hive then it would look like this.
As I checked further, looking at the logs, mapping the correlation ID to log contents it seems that the Microsoft.SharePoint.WebControls.AspMenu.OnMenuItemDataBound was the culprit.
But why? there is nothing wrong with my menu? So I went back to the old Sharepoint and check the Navigation items, namely the Quick launch and the Top Link Bar.
Then I found this.
A blind link? will this be the reason? If that’s the case how do I fix it I can’t even go to the site, the site settings would not show. Well you can do it manually by going to SQL and look for all blind links you know like “http://#“. To do that go to your Sharepoint SQL Server and on the WSS_Content Database look for [NavNodes] which keeps all the navigation links on your Sharepoint, you can join that then to [AllWebs] table to get the URL where the link is stored. So your query should look something like this.
SELECT n.Url, n.Name, a.FullUrl, a.Title FROM [WSS_Content].[dbo].[NavNodes] n INNER JOIN [WSS_Content].[dbo].[AllWebs] a on n.WebId = a.id where n.Url like '%#%'
From here I guess you can update it and figure out what new link to give it, then your site should run fine.
So in a nutshell it looks like Sharepoint 2013 dont like this blind links unlike Sharepoint 2010 where it accepts it as a value on creation.
