If you force refreshing the page (Ctrl+Shift+R, or Cmd+Shift+R on Mac, like when forcing refreshing thumbnails on a movie page after updating the pictures) you should get the new version.

edit: but maybe don't do it right now, it seems something is broken

I have yet to refresh this page

This layout came up like this:

Yes there is something broken. The forum owner most likely made a mistake while fixing some details that I mentioned to him, and now we have to wait for him to come back

My laptop would like to thank rjluna for his post... you just saved him a trip through the nearest window..

It is now fixed

I still have the old layout

I have the new layout since a few days ago, and it's so... white. On my laptop, the columns are barely visible.

Which columns you mean? Lines between blocks on the page?
it is indeed a lighter style.

I should maybe split this thread to create one for the forum with the last messages.
