"Refused to display document because display forbidden by X-Frame-Options." is displayed in the console of Chrome and the photo uploading from Flickr gets stuck always in my local wiki. Not sure if this is a bug or not though.
See http://www.mediawiki.org/wiki/Extension:UploadWizard#Installation, specifically the part about $wgApiFrameOptions.
