Checking the nonProxyHost Settings for the Theme Editor 

Use

If the Preview function for the themes does not work correctly in the Theme Editor, you must check whether the portal is configured with the correct nonProxyHost settings in the service configuration.

Procedure

...

       1.      Check the nonProxyHost settings.

       2.      Start the proxy service again.

For the precise procedure, see Note 602336.

To check if your settings are correct, start the Theme Integrity Tests and run the test „Serverside URL Connection Test“. If the nonProxyHost settings are not correct, the test displays an HTTP error.
