Just to let you know that when using Contact Form 7 to Database Extension with Fast and Secure Contact Form, and having also Contact Form 7 installed and being used (but not with the database plugin), the Contact Form 7 forms hang when using them, the arrow icons keep rotating and no confirmation message shows, even though the emails are being send through the form.
I was able to solve the problem by editing the CF7DBPlugin.php in the Contact Form to DB Extension and commenting out the line:
add_action('wpcf7_before_send_mail', array(&$this, 'saveFormData'));
It would be good if the plugin had an option for this on the menu.
Also, I changed the plugin to insert the form input directly into the wp_posts table, so they became common editable posts. I did this for custom posts, works great. It'd be really good if the plugin allowed for this directly.
Thanks for the excellent work.
