I've just upgraded to 3.8.4 version, when I upload a new one picture from the backend, the file result uploaded, but obtain a white Media window as screenshot.
I've customized the media path for files and images as shown:
And set the Joomla max limit upload to 10MB
Could this one create the problem?
