How to find errors that referenced in Error logs?

Question

I am one of the Sitecore developer of a large Sitecore site, I have been assigned to clean up a project that cleans up a lot of the error logs, These are the errors logs, but since I am new to the project I cant find where these data sources are referenced, also this is a huge site, so clicking each item and checking is not a go.

Logs

Answer 1

You could do this with the Broken Links report in Sitecore PowerShell Extensions.

• Install the latest version of Sitecore PowerShell Extensions

• In the reporting menu, find the Broken Links report:

• Select the home page or site root you want to search. Make sure you only select Internal Links:

• Look in the report for broken links in the __Final Renderings field.

That will give you all the places where a datasource item is being referenced, that no longer exists. As for fixing, that is probably a more manual process.
