New sidears not working

Hi,
This is strange. I am using this plugin for few months. I created long time ago a sidebar and assigned it to a category, and it works fine so far.
The problem is when i try to create new sidebar and assigned it to page, category,template anything it won’t work no matter what.
I also tried to add a new category to the sidebar i had created few months ago, nothing. It displays only the primary sidebar of my theme at that category.

My theme also supports adding sidebars with limited functionality, so i tried to add a sidebar from theme options or hide sidebar from homepage, absolutely nothing! No changes at all.

I guess a conflict or something.

Any help would be appreciated.

*I am using the premium theme Sahifa.
