email button problem

I love this plugin but am having a problem with the email button.

This text is displayed in front of the email button on my website.

Home&Body=I thought you may be interested in this site.%20http://localhost/mysite/”>

(the part after Home&Body= and before %20 is what I entered as ‘email text’ on the ‘advanced’ tab of the plugin settings).
Also, this shows up in the subject of the email when the icon is clicked:

<span class=

Any help would be greatly appreciated!
