The date picker in this plugin is out of date and needs to be replaced. Here's my fix:
Go to line 697 of the verve-meta-boxes.php file and insert the following lines of code:
wp_enqueue_script('jquery-ui-datepicker'); wp_enqueue_style( 'jquery-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/themes/base/jquery-ui.css' );'
Go to line 15 of the verve-meta.js file and replace it with the following line of code:
Enjoy your working date picker.
Note to the authors: feel free to integrate this.
