Problem with uploading modified site with Muse CC

Hi,

When uploading my site, everything is out of place on the home page and a product page. I get the following message :"MuseJSAssert: Error calling selector function:TypeError: $(...).toBrowserWidth is not a function" on these two pages, the other ones are fine.

I initially uploaded it through Muse. When it didn't work, I tried uploading with Dreamweaver, Filezilla and Cyberduck, to no avail... I get the same result every time.

I checked that all my assets were correct and they are.

It works perfectly when I publish to BC.

I am at loss of what to do. Can anyone help ?

Thanks !
