Hello again,
I decided to start a new topic since you completeley ignore the previous none.
So the problem is that even if you enable the forum sidebar from the theme options
and even if put some widgets in the forum sidebar area, the sidebar will not work
and it will show blog sidebar instead.
Since this is a theme related bug you should find out a way to make it work.
(I noticed tha in your site 8theme.com there is a different sidebar in the forum)
Please dont ignore me
