Is there anyway to allow access to make changes on this file? We have the same setup within our Magento theme and we really need to make changes to a CSS file, however, when we make the changes and reupload the file, nothing changes and file reverts back to how it was before. Would you know of a way we could by pass this so we can make the necessary changes in our CSS file?
