When I add a widget to the Primary Aside in the Sidebar, the Search form disappears. Although Search is listed as a widget, it is not available for re-installation; it is just gone.
I encounter the problem when I installed the plug-in, Add-to-Any-Subscribe, so I thought it was an expendable widget and, therefore, not a problem. But adding a Category or Calendar widget does the same thing. Am I doing something wrong with my widgets?
