HTML export problem

  • Hi,
    I try to export in html5 (preview mode or real export) but i have a big gray square in front of all the element. The problem is that i have no element like this... I try to export video and it is fine. But not in html5. Someone have this problem too ? My windows is 1600x1000 px and the background image is 1600x2500px.
    Many thanks for your help and support !

  • OK i found what the problem was : i must not use special caracters or accent in the name of the layer. That's all :)
