Question: Safari unable to upload photos in Facebook.
OS X 10.11 and Safari. The latest security update was just installed. Unable to upload photos as part of a Facebook post. It worked before applying the security update. Google Chrome works fine. Attempts to rectify the problem include installing the current version of Flash and the current version of Java. Confirmed that both were toggled ON in Websites preferences within Safari.
