Thanks for help .
But I thin you misunderstand what I mean :
I do not mean how to choose which sidebars are displayed .
I mean how make sidebars displayed in the left side.
By default GP theme sidebar appear on right, because it is for English blogs, but I have Arabic blog which is RTL , so I want it to be displayed in the left side .
I hope you understand what I mean and help me .
Thanks in advance .
