Any idea?

Hi,

Please attach here a minimum blend file which causes such error. Thanks!

here it is.

[UPDATE] Even with default scene i got the error
- Firefox 46.0.1 –> Error
- Chrome 50.0.2 –> No problem
- Edge 25.10586 –> No problem

i think i found what cause the problem, the viewer says me that the version is 16.05 :p
How to solve this?

Thanks

the viewer says me that the version is 16.05 :p

This is ok, the dev version of the viewer and apps always report current date as version. You can check this by running a compiled version.
Still having such an error for the default cube is strange. Please provide info about your system: OS, video card, driver. Thanks!

Unfortunately, we cannot reproduce this bug on exactly the same configuration.

This seems really strange, because the default scene with a simple cube hasn't shadows and the SHADOW_CAST subscene shouldn't be rendered.
Can you attach here the full console output for the default scene?
