Without a shadow of a doubt, Nivo Slider is one of my favorite plugins for WordPress. Nivo Slider basically acts as a slide show for your website.  It is very easy to install and implement. Dev7studios updated their Nivo Slider a few days ago (from 1.8 to 1.9), but it created a flurry of errors for its almost 2 million users.

The update causes the slider to break and display the following error:

Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in wp-content/plugins/nivo-slider/nivo-slider.php on line 1572

To fix the Nivo Slider bug, simply:

  1. log into your WordPress admin panel
  2. On the left sidebar of your Admin panel, click ‘Nivo Slider’
  3. For each slider you have set up and want to fix, click ‘Edit’
  4. Once on the specific slider page, DO NOT CHANGE ANYTHING.
  5. Hit ‘Update’

That’s actually all you need to do. Go to your webpage that uses the slider and refresh it to see the fixed Nivo Slider. Easy as pie!
