Gantt view layer change

Hi All,

We upgraded Sharepoint from 2007 to 2010. Than we saw, the Gantt view change in 2010. Until this time (in 2007) task list was under the timeline, and now in 2010 is next.

I tried this solution, but doesn't work, and we are looking for the other solution, because this Sharepoint Solution do that 2010 change style to 2007, but only main site, but the subsites don't change.

Have anybody other solution to this problem?

Thank you!
