Config file not found error in Chrome/OSX
But in the past 3 hours the program has crashed at least 4 times with the "Config File not found" error...
I'm not sure if you are referring to the "Config file not found." message appearing in your Chrome browser or Lightroom's live preview window (or both).
If the error message appears in your Chrome browser, then please see this FAQ which refers to the error message and might help.
When I view my gallery I see the message 'Config file not found'. How do I fix this?
Also, if possible, please upload the gallery to your web server and post a link so that I can take a look at the problem for myself and hopefully help further. Once I am able to see your gallery and its code, I should be able to determine the cause of the problem and propose a solution.
If the error message appears in Lightroom's live preview window then the try forcing a refresh of the page (by pressing Cmd+R (Mac), Ctrl+R (Windows) or by selecting 'Web -> Reload' from the drop-down menu at the top) to see if this clears the problem without having to move away from the Juicebox web engine and lose your settings.
Over the course of a year and a half, only three other users have reported the "Config file not found." message appearing in Lightroom's live preview window. Two of these users are known to be using a Mac (the third user's system is unconfirmed) but I've never been able to replicate the problem myself on a Windows PC. From the limited information I have, it seems that the problem may affect only a limited number of Mac users.
Maybe my notes in these forum threads will at least help to explain this issue in greater detail:

As I mentioned in the forum threads above, the problem could be some kind of timing problem with the way that Lightroom generates the files for the preview (perhaps the 'config.xml' file is sometimes not ready in time for the gallery to be displayed by the 'index.html' file).
In the plugin's manifest file, the plugin requests that the 'config.xml' template be processed before the 'index.html' template so, unless there is some kind of threading issue or asynchronous activity (which, as far as I am aware, the plugin has no control over), I'm really not sure what might be causing the problem.
Please let me know if refreshing the live preview window when the error message appears (Cmd+R (Mac), Ctrl+R (Windows), 'Web -> Reload') helps.
