We use FSC Contact Form plugin.
Whenever the contact form is sent from a Portfolio post, it malfunctions. eg: http://www.hummingbirdhall.com
However, whenever the plugin is embed in a page, it works fine, eg: http://www.hummingbirdhall.com/quotation/
Is this a known bug? Are there any fixes? Are there any form plugins that will work with portfolio posts that can be recommended?
