Q: After enabling the settings, my site doesn't have any style, it's just text. Why? A: Your site can't find your theme files, be sure you've uploaded them to Dropbox, and preserved any folder structure it contained.
Q: Is this an official Dropbox plugin? A: No, I am in no way affiliated with Dropbox.
If you have questions please leave them in the comments at the plugin homepage.
