In SharePoint, the “500 – Internal Server Error” might occur in case:

  1. The Web config file might have been modified in incorrect format.
  2. An Application Pool is stopped.


The Web config file was modified in incorrect format
  • Open IIS Manager.

Open IIS Manager

  • Try to browse the SharePoint site.

Browse the SharePoint site from IIS

  • The error details should be now displayed as shown below.

In the above case, I forget to surround the attribute value with a double quotation.

Note: It’s heavily recommended to take a backup from the Web.Config file before performing any update to allow a rollback.

  • Locate the web config file by browsing the SharePoint web application as shown below:

Explore Web site in IIS Manager

  • Edit the config file with an appropriate editor.
  • Save and close.
  •  Repeat all previous steps for all Web config within the SharePoint servers.
  • Try to browse the site again that should be working correctly.

An Application Pool is stopped.
  • Open IIS Manager to make sure that the application pools were running,

  • If you found out the web application pool has been stopped, try to start it.

This behavior usually occurs in case the password of Application Pool Identity has been changed from Active Directory.

Unfortunately, this change is not automatically reflected on the IIS Application Pool and requires to be updated manually in IIS Manager, by doing the following:

  • Right-Click on the Application Pool > Advanced Settings.

App pool - Advanced Settings

  • Below Process Model > Identity.

  • Update the Application Pool Identity credential as shown below:
