Hi Brenden,
Thank you for your reply,
I figured out the reason of this issue. I missed rename the jquery-core.js.new file in CMSScript/jquery. I changed the name of this file and Site manager work correctly. However, I still have a problem with embed jQuery-ui(\CMSScripts\jquery\jQueryUI\jquery-ui.js) to site. So please suggest a best solution for me.
Thank you again!
