When i click on any picture it opens the semi-transparent black background but empty with no picture, navigation arrows, close button, anything. And you cannot even close or go away from this screen.
Tried with Chrome, Safari, Firefox, Opera (all the same behaviour)
Watching the error console in safari gives this result:
TypeError: 'undefined' is not an object (evaluating 'fsg_json[postid].length') galleria-fs.js:129
Any help how to fix it to work properly and show the images?
