Contact Form 7 Newsletter not Integrating with Constant Contact. Form is working, but mailing list subscribes do not show up in Constant Contact

[jnicoll4]

This error occurred since updating to WP 3.9:

The integration between our contact forms and constant contact is not working. We still receive the filled out forms in our email along with what mailing lists they would like to join. However, when looking at the Constant Contact contacts, the new subscribes have not automatically been added.

When looking at the Contact form 7 Newsletter plugin on WordPress, I can see an error where the integration fields show up.

The drop downs for each field are now blank. When I click the down arrow I see the following message typed long ways in the drop down menu:

Fatal error call to undefined method wpcf7 shortcode manager instance in /wp-content/plugins/contactform7newsletter/shortcode.php on line 30

Also, when submitting a form on our website, the following error appears at the top of the web page:

Warning: strpos() expects parameter 1 to be string, array given in site path /public_html/wp-includes/shortcodes.php on line 193

Is this problem being looked into? Is this due to the update of wordpress to 3.9? When can we expect a fix?
