My wordpress site does work on all type of phone’s, but the sidebar doesn’t show up. Is there a plugin that makes my site completely compatible with any phone or at least android and ios? i tried DudaMobile but that didn’t work, that plugin said that my website didn’t exist.
A responsive theme adapts to different screen sizes automatically and is recommended if you need to attract a mobile/tablet market. A good example is http://wordpress.org/extend/themes/responsive
The default 2012 theme is also responsive.
