Contact Feature Not Working Again on Jobs & Experts Plugin

I am using the Business Feature Theme. The contact feature is not working again on the Jobs and Experts plugin. When you attempt to contact an expert, the message composition part works fine (you can attach an image, url, content, etc) but actually sending the message does not work.

In addition, contacting an employer does not work at all. The blue "contact" button is not hyperlinked and is not clickable.

I thought that this issue had been addressed when I last noticed it occurring about over a month ago? Reference:
