Array Error

When I activate the plugin, I get an array error.
Can you tell me how to fix this or is there another version that works better? My WordPress version is 4.2.4 and I downloaded plugin version 4.0.

Here is the error:
Warning: array_values() expects parameter 1 to be array, null given in /home/spraywor/public_html/wordpress/wp-content/plugins/wp-quick-front-end-editor/plugin.class.php on line 269

Warning: array_values() expects parameter 1 to be array, null given in /home/spraywor/public_html/wordpress/wp-content/plugins/wp-quick-front-end-editor/plugin.class.php on line 120

Thanks!
Jennifer
