WordPress SEO by Yoast - Plugin (Current version as of this morning).
I've imported settings before on a single installation of WordPress running 3.1 beta 2.
I am now trying to import the settings file on a Multi-Site install running WordPress 3.1 RC 1. I get the following message "Settings could not be imported: Upload failed.". Thought I would post it here as it's not a major big deal but certainly could be a bug.
