Created attachment 281661 [details] Empty inspector All tabs are completely empty and never update with data. Have tried restarting Safari, but the Web Inspector is non-responsive. I've been trying to use the Safari Web Inspector in place of the Chrome dev tools, but so far it has been a less than pleasant experience.

Can you clarify what revision of WebKit / Safari this was? System Safari, WebKit Nightly, Safari Technology Preview?
Safari 9.1.1 (11601.6.17)
• Does the issue reproduce on every page? • Does the issue reproduce for you in WebKit Nightly or Safari Technology Preview? I highly suspect you are running into some kind of uncaught exception in the inspector frontend. There are some steps you can run to provide us with more information. Would you be willing? (The steps are mostly on <https://wiki.webkit.org/wiki/WebInspectorDebugging>).
Namely, I think you can enable these defaults and restart Safari. defaults write com.apple.Safari "com.apple.Safari.ContentGroupPageIdentifier.WebKit2LogsPageMessagesToSystemConsoleEnabled" -bool YES defaults write com.apple.Safari WebKitLogsPageMessagesToSystemConsoleEnabled -bool YES defaults write com.apple.Safari WebKitDebugLogsPageMessagesToSystemConsoleEnabled -bool YES And then check syslog (Console.app) for some output. You can then do -bool NO and restart Safari to disable the logs.
We lack insufficient information to proceed with this bug. Please reopen if you are able to provide Joe with some more information.
