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:
- log into your WordPress admin panel
- On the left sidebar of your Admin panel, click ‘Nivo Slider’
- For each slider you have set up and want to fix, click ‘Edit’
- Once on the specific slider page, DO NOT CHANGE ANYTHING.
- 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!
