Full width?

[Genestoy]

I just upgraded my test forum from 4.1.9 to 4.2 and now the main/topic part of the board are not full width with fluid width enabled to 100% (logo is fine) what happened and how to fix it? I recall someone else here had the same problem after the upgrade but can not find that post.

Thanks

Never mind, it was a browser cache issue
