[Plugin: Special Text Boxes] Animations don't work

This is a great plugin, although I can’t get it to work on my site.

The boxes display, but the animations for open close etc do not work.

[ Moderator Note: Please post code or markup snippets between backticks or use the code button. ]

[stextbox id="alert" caption="This is example of Customising on the Fly" color="000000" ccolor="ffffff" bgcolor="f7cdf5" cbgcolor="f844ee" bcolor="f844ee" image="http://www.simplelib.com/wp-content/plugins/wp-special-textboxes/images/heart.png"]This is example of customised alert special textbox. This short code inserted with id “alert” and customised with short code options.[/stextbox]

[stextbox id="info" defcaption="true"]Some text[stb id="download" defcaption="true" collapsing="true"]Some text in the indoor box[/stb][/stextbox]
