Sorry something went wrong the file masterurl custom.master is not a valid master page

In this post we will discuss how we can resolve the master page issue which comes while opening a SharePoint 2013 site. Recently when I opened a SharePoint 2013 migrated site, in one page it gave me an error which says:

Sorry, something went wrong
The file ‘~masterurl/custom.master’ is not a valid master page.

Solution:
Open your SharePoint 2013 page using SharePoint 2013 designer. Then you will be able to see a tag like below:

<%@ Page language=”C#” MasterPageFile=”~masterurl/custom.master”

Sorry something went wrong the file masterurl custom.master is not a valid master page
Sorry something went wrong the file masterurl custom.master is not a valid master page

Now here change custom.master to default.master in the MasterPageFile tag.

<%@ Page language=”C#” MasterPageFile=”~masterurl/default.master”

It should look like below:

Sorry something went wrong the file masterurl custom.master is not a valid master page
Sorry something went wrong the file masterurl custom.master is not a valid master page

Now Save and Publish the page and then refresh the page, the error should not come.

Hope this will be helpful.
