I installed the plugin. I can add the widget and define a title for the search field. The title apears, but not the form-field: http://www.gzroos.ch/
Any idea? Your plugin is exactly what I want.
Kind regards from Switzerland
In our servers it works properly. The widget should be displayed as it is on the attached screenshot.
Maybe there is a plugin collusion in your environment. Please deactivate temporarily the other plugins and check if the widget is shown.
