500 Internal Server Error. This browser is not supported – Error in Enterprise Portal in IE 11

Overview :

A Webdynpro application is integrated in the Enterprise Portal to display the backend application to the end user

Recently, on upgrading/updating ECC or backend and on launching WD ABAP application in portal error is seen as 500 Internal Server Error. This browser is not supported, on launching from Internet Explorer 11.

 

 

Environment :

  • Enterprise Portal on SAP NetWeaver Java
  • WebDynpro ABAP

 

Cause :

The issue is caused by the application running in Quirks mode and going forward it will support Standards mode of rendering.

 

Solution :

The KBA # 2424773 – Display and Rendering issue in IE 11 in Portal, deals with the steps to solve the issue.

The KBA has a quick test in the Cause Part, to check the requirement of the application in the browser via Console tab of the browser.

To solve the issue one of the below solution can be implemented in Portal

  1. To make the portal run in standards mode by making use of the framework page – Ajax standards mode framework.
  2. Changing the Launch in New Window” attribute (for iviews/pages) to “Display in separate headerless portal window (standards mode)”

 

End of Quirks Mode Support for Internet Explorer :

Starting from NetWeaver 7.52 and/or SAP Kernel 753 and/or SAP_UI 7.52 used in lower NetWeaver AS ABAP versions, Quirks Mode (IE 5.5 rendering mode) of Internet Explorer is no longer supported by SAP for all SAP UI technologies (the SAP release date is planned for the end of Q3/2017) and cannot be executed anymore.

If you use Enterprise Portal 7.50, change your framework page to Ajax Framework Page standards mode (AFP Standards) or Fiori Framework Page.
