jQuery plugin (sidebar) and category's content page having conflict

Hi!

At the moment I’m not fully used to wordpress blog’s all functions, so I have some difficulties with adjusting my childtheme to work fine.

I uploaded jQuery sidebar plugin (mb.extruder, check pupunzi.com if you want to) where I was meant to put some widgets. Well, it works ‘fine’ on other pages, except here: oma-tila.net/blogi/category and oma-tila.net/blogi/author. I had in mind that both sidebar and site’s content are calling the widgets, but I have no idea why. Is it caused by that the sidebar and those sites have bot part called ‘content’ or etc?

Here is what should the site look like in reality: oma-tila.net/blogi/

I’m also wondering, how to modify those widgets? Problem is that I don’t know how to refer in those with css in a way that doesn’t have influence on nothing else than widgets.

If someone could help me, I would be very grateful.
