Opened: May 22, 2018

Severity: 3-Major


If you create a Web Application Security Policy with the application language set to 'auto-detect' and try to update it to another value, it fails with an error. The error appears similar to the following: applicationLanguage is set only once, and should not be changed. Existing value: auto-detect, New value: utf-8.


The save fails with an error.


The issue happens when using auto-detect language.


To work around this issue, delete the policy and recreate it with a different application language.

Fix Information

It is now possible to set application language.
