 * I am not sure what is wrong. I’ve set the plugin up with the API keys, recipient,
   and subject, but I get the message “An unexpected error occured. If this problem
   persists, please contact the webmaster.”
 * (Also, occurred has a double r.)

 * Hey there,
 * thanks for you feedback. The error occurs when WordPress isn’t able to send the
   mail through its wp_mail class.
 * so your reCAPTCHA configuration is correct, at least.
 * things you can do:
    - double check the recipient (unlikely though)
    - can your wordpress setup send emails anyway?
    - enable wp_debug in the wp-config.php and check the output after trying to 
      send the contact form. You may have to look at the source as well
    - If you are an advanced user, you may check your server logs
 * Thanks for the typo, this and spam-filtering will be fixed in the next update.
 * To be honest, we already tested the plugin against WordPress 4.3 and run it on
   several bigger installations. As rude as it sounds, its probably an issue on 
   your end.
 * sincerely,
    Pascale

 * It doesn’t sound rude at all. I am quite sure that it is at my end. I don’t think
   the php mail function is installed. I’ll go at it and report back.
 * As it is now, I do think your plugin is gorgeous. Nice, simple, and light. I 
   just need to get my system working.

 * The wp_mail class is shipped with WordPress itself.
 * Feel free to drop me a mail at [mail@pascalebeier.de](https://wordpress.org/support/topic/error-not-sending/mail@pascalebeier.de?output_format=md)
   and send me a link to your Website.

 * OK folks, here was the issue.
 * My LAMP setup had no email functionality installed. After looking into the options,
   I decided to install postfix (which is a newer solution over the decade’s old
   sendmail).
 * For those in the same boat, try one of the following tutorials, depending on 
   what you want your server to be able to do.

 * If you don’t know if you are in the same boat, via your terminal, type
 * dpkg -l
 * and look for either postfix or sendmail. If you don’t see them, well, programs
   that don’t exist cannot send email.
 * As for the plugin, it is functioning beautifully.

 * Thanks for posting the solution.
 * This motivated me to clarify the error messages to track down errors faster.
   
   Maybe someone stumbles on the same problem as you and finds help here!
 * Sincerely,
    Pascale
