Wordpress Contact-Form-7 Not Sending–”Spinning Arrows”

I recently had an issue with a new Wordpress install, where the Contact Form wasn’t sending correctly, instead hitting the Submit button would simply show the Spinning arrows animation, with no Mail Sent.

I was also using the Really Simple CAPTCHA plugin, which may have had a bearing on the issue too.

After doing some digging around I found a couple of forum posts which helped;

http://wordpress.stackexchange.com/questions/13367/how-to-resolve-failed-to-send-your-message-problem-for-contact-form-7

Combining these two gave me a solution which worked;

1. Set the Permissions of the “wp-content/uploads” directory to 777
2. Open the “p-content/plugin/really-simple-captcha/really-simple-captcha.php”
   
   Change;
   
   

   /* Image type. 'png', 'gif' or 'jpeg' */

           $this->img_type = 'png';

           /* Mode of temporary image files */

           $this->file_mode = 0444;

           /* Mode of temporary answer text files */

           $this->answer_file_mode = 0440;

   
   To;
   
   
   
   
   

   /* Image type. 'png', 'gif' or 'jpeg' */

           $this->img_type = 'png';

           /* Mode of temporary image files */

           $this->file_mode = 0777;

           /* Mode of temporary answer text files */

           $this->answer_file_mode = 0770;

   
   
3. Install the “WP-Mail-SMTP” plugin and configure it to use your website’s email address smtp settings etc
   
4. Modify your Contact-Form-7 Contact Form settings;
   
   From:
   
   
   To:
   
   
   Where you should replace “info@yourdomain.com” with the email address you have configured in the “WP-Mail-SMTP” plugin.

Adding the Additional Headers, allows you to still reply to the original sender.
