 * Hi got it to work!
    I have a child-theme, and the entire “SketchBoard” folder
   from the original “biznez-lite” theme was copied into my child-theme folder. 
   So naturally, during upgrade, that copy I made did not get updated…
 * Copied the new “biznez-lite/SketchBoard/functions/sketch-theme-support.php” file
   into the “SketchBoard/functions” folder in my child-theme, and all is well 🙂
 * cheers!!

 * Hi Chink,
 * You are facing this issue due to change in the function prefix from `skt_nav()`
   to `biznez_nav()` in new version of `BizNez-Lite` which were recommended by the
   WPORG theme review team. As you already told me that you are using child theme
   and you have copied functions from `function.php` from parent theme to `functions.
   php` of your child theme. Now the new functions which were used in new update
   are not available in your child theme’s `function.php` file. To fix this issue
   you have to copy functions form parent theme’s ‘functions.php’ to you child theme’s`
   function.php` file once again.
 * Best,
