Hi,

Thank you for your message.

The impact would be quite devastating if you use frames or any other jQuery functionality. If the Kentico generates its itself you couldnt remove them anyways without changing a lot of code (in source code also).

Unfortunately there is no way to fix this as if the scripts are generated by Kentico you should never attempt to remove them.

Kind regards,
Richard Sustek

Hi RichardS! I have a question: If I can't remove files script are generated by Kentico,can I compress them? ex : jquery-core.js, jquery-dialog or jquery-ui...

Thank and Best Regards!

Hi,

Thank you for your message.

Actually yeah, we have thought of this aspect and you can see that all our scripts are getting through GetResource.aspx page. If it goes through this page you can increase performance by going to Site manager -> Settings -> System -> Performance the Resources section. You can compress these scripts and minificate them.

Kind regards,
