How To Open a Popup Form On Page Load

As you already know, the shortcode to embed a popup form is:

[fc id='1' type='popup']Click Me[/fc]

To auto-open the popup form on page load, add the attribute auto=’0′ to the shortcode:

[fc id='1' type='popup' auto='0']Click Me[/fc]

To auto-open the popup form 4 seconds after page load, add auto=’4′

[fc id='1' type='popup' auto='4']Click Me[/fc]
