 * Installed the plugin, activated it, input my redirect URL, saved everything.
 * Upon refreshing my desktop/main site, I get this:
 * Fatal error: Call to undefined function wp_is_mobile() in /home/content/s/t/r/
   myusername/html/wp-content/plugins/simple-mobile-url-redirect/mobile-redirect.
   php on line 172
 * What’s that all about….
