Thread:Extension talk:SmoothGallery/MW1.15 Not Working - Images on top of each other/reply (2)

I have the same result in MW-1.17wmf1. All the pictures are on top of each other. However, when I press button Show preview I got normal gallery layout like in wiki/Special:NewFiles (Gallery of New files). When I save page I have the problem. How to check that all JS are loading?
