Could you please right click or ctrl+ click on the empty area and select all the missing panel from the flyout menu.
If the side panel is visible and completely empty, open the Window->Panels Menu and put checkmarks in the ones that you want displayed. Alternatively, you can just press Ctrl/1-6 to bring back the different sections. If the side panel is gone, click on the little gray triangle midway down the right side of your monitor screen. Click twice to make it stay displayed.
no, it only gives me background color options
Thank you. It worked.
