Client Script field is disabled

[AymenBM]

Hello,

I am getting this message when I try to create a new 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.

I have added the "Isolate Script" field but I have always the same problem (see attached).

Can you help me please !

Thank you very much for your help!

Is it happening only for this client script or for all the client  scripts?

Thanks.

Can you go from the native UI to the client script:-

Do the below:-

In navigation type Client script:-

Then from the list of Client scripts opened open anyone any check if the script portion is editable or not. 

Please mark answer correct/helpful based on Impact

Thank you.
