Display Error page xpages not working

I want to set display default error page in Application Properties under the xpage tab.

Nothing happens when I click the checkbox.

All other properties are ok to set, but the xpage properties are not changeable.

This is on the server database so I assume it is a security setting somewhere.

On a locla copy I can chenge the setting.

Please advice on what to do.

Subject: Is there anything particular about your access to the server db, or even the db itself?

Also, the Application Properties edits appear in the xsp.properties file. The best way to see this is launch the Package Explorer view in Designer and then on the App navigate to WebContent/WEB-INF/xsp.properties

Here if you access is correct ‘xsp.error.page.default=true’ should be here.
