I have used Contact form-7 with other WP themes before and had no problems setting it up. However, on this new project the form is not showing up on the page, only the shortcode appears [contact-form-7 id="1143" title="Contact form 1"]. See http://blacksheepreggaeband.com/about-us/contact-us/ for an example of the problem.
I contacted the theme author and after reviewing my site using WP admin and my error logs this is his comment [There seems to be a compatibility issue with your server and the plugin, If i enable the default wordpress theme the error remains which usually shows either a host server setting or plugin error. The best would either to make contact with your host or plugin author.]
I am using WordPress 3.3.2 . Please help. Thank you.
