Customising Error Page in Sharepoint 2013

Normally within SharePoint if an error occurs we would be receiving quite an unhelpful error message i.e. “An unexpected error has occurred”. It is because by default the detailed error messages are turned off for security reasons.

Here are the steps for getting the full error messages

1)      Go to the SharePoint site for which you would like to enable it.

Most likely to be found at c:\inetpub\wwwroot\wss\VirtualDirectories\... and a sub directory with your web application’s port number.

2)      Locate and open the web.config file for editing.

3)      Find out the following entry

<SafeMode MaxControls=“200“ CallStack=“false“ DirectFileDependencies=“10“TotalFileDependencies=“50“ AllowPageLevelTrace=“false“>

And make following changes to it

<SafeMode MaxControls=“200“ CallStack=“true“ DirectFileDependencies=“10“TotalFileDependencies=“50“ AllowPageLevelTrace=“true“>

4)      And

<customErrors mode=“On“ />

To

<customErrors mode=“Off“ />

5)      Save and close web.config.
