That is fine. The reason you are getting the warning is that its hash does not match the hash of the original.
We accept JQuery/JQuery-UI libraries downloaded from ‘ajax.googleapis.com’, ‘jquery.com’ or ‘jqueryui.com’; and used without any modification. Minified versions are better. (file-name change does not matter)
I’m sorry, but we cannot accept modified, re-configured or customized libraries.
If you copy the code and paste it in the new file, it will change its hash.
