Hi. It worked well for this website... the only problems are
1) In despite that I'll have to keep an eye on every plugin update to add the patch....
2) The core problem is that it is within a multisite install, so the id for one contact form in this site, may be any other important page in other website..
I thought on hiding the div via CSS, but the Elegant Theme in use is not setting the class id in the body tag, so I'm unable to distinguish individual pages via CSS :(
Is there any shortcode or thing usable to do this without having to touch the original plugin files? If not, may this set a precedent to ask for a feature request? :)
