client script is not working. "version : Washington"

Getting error in client script 

New client-scripts are run in strict mode, with direct DOM access disabled. Access to jQuery, prototype and the window object are likewise disabled. To disable this on a per-script basis, configure this form and add the "Isolate script" field. To disable this feature for all new globally-scoped client-side scripts set the system property "glide.script.block.client.globals" to false.

What is your question? You are sharing the message that is on every client script (for a few versions now) to explain what you can do. This is an info message. Not an error. If you open the form view, you will see the annotation box with the message.

You say a client script isn't working. That has nothing to do with that message (although the message could help you in resolving it).
What is your client script? What is it supposed to do? What does it do?
