Plugins that store transient data using your site URL
Some plugins (such as Easy Social Share Buttons) store transients in WordPress’s options table and include your site URL as part of the transient name. This can cause problems when you create your staging site name with a longer URL than your live URL because these transients get truncated and become non-unique, which causes problems with the database. For right now, try choosing a very short staging site name (two characters) and see if that fixes the problem. We are working on a more thorough workaround, but do not have an ETA.
