As a work around go to your plugins folder and change lines 160 & 174
in file /wp-content/plugins/contact-form-7/includes/contact-form-template.php
To this: There was an error trying to send your message try to disable Block followers or Anonymous browsing or resize images if uploading. If none of these steps work please email your form to Your-Email@Your-domain.
Maybe a new plugin is the answer any suggestions? as this is not going to be fixed anytime soon as this is a free plugin.
We have the same problem it has been going on for months without resolve, some users can send the form others are not able! PLEASE FIX THIS PRODUCT. They just get the standard error try later. We use the captcha still the same without it lot of unhappy word press users.
