I got this message what should I do about it, what do they mean by upload to the server:
It means that you have added something to your page that requires the use of code in an external file. In your case it appears that you have added some jQuery effect or widget to your page. For this item that you have added to function properly, you need the library of jQuery code to be associated with the page. The alert is telling you that this jQuery file has been copied to your local site, and must also be uploaded when you upload the file for the remote (live) file to work properly. This is normal for any of these kinds of effects.
