I have created one document library in SharePoint 2013. On uploading the same file SharePoint throws error as"server error. The same file exit".
But my requirement is not to show the SharePoint default message. I wanted to create custom message and show the pop up for the same file upload.
Is there any way to create any custom error page or can I manipulate SharePoint default error page?
Basically I want to change the above message to a custom message.
