Nothin happening!

Managed to get it working….kinda!

Go to your plugin folder > WP-Job-Manager > Templates > job-application.php

Replaced:

<div class="application_details">
			<?php
				switch ( $apply->type ) {
					case 'email' :

						echo '<p>' . sprintf( __( 'To apply for this job <strong>email your details to</strong> <a class="job_application_email" href="mailto:%1$s%2$s">%1$s</a>', 'wp-job-manager' ), $apply->email, '?subject=' . rawurlencode( $apply->subject ) ) . '</p>';

						echo '<p>' . __( 'Apply using webmail: ', 'wp-job-manager' );

						echo '<a href="' . 'https://mail.google.com/mail/?view=cm&fs=1&to=' . $apply->email . '&su=' . urlencode( $apply->subject ) .'" target="_blank" class="job_application_email">Gmail</a> / ';

						echo '<a href="' . 'http://webmail.aol.com/Mail/ComposeMessage.aspx?to=' . $apply->email . '&subject=' . urlencode( $apply->subject ) .'" target="_blank" class="job_application_email">AOL</a> / ';

						echo '<a href="' . 'http://compose.mail.yahoo.com/?to=' . $apply->email . '&subject=' . urlencode( $apply->subject ) .'" target="_blank" class="job_application_email">Yahoo</a> / ';

						echo '<a href="' . 'http://mail.live.com/mail/EditMessageLight.aspx?n=&to=' . $apply->email . '&subject=' . urlencode( $apply->subject ) .'" target="_blank" class="job_application_email">Outlook</a>';

						echo '</p>';

					break;
					case 'url' :
						echo '<p>' . sprintf( __( 'To apply for this job please visit the following URL: <a href="%1$s">%1$s →</a>', 'wp-job-manager' ), $apply->url ) . '</p>';
					break;
				}
			?>

		</div>

With:

<div class="application_details">
	<?php
		switch ( $apply->type ) {
			case 'email' :

				echo '<p>' . sprintf( __( 'To apply for this job <strong>email your details to</strong> <a class="job_application_email" href="mailto:%1$s%2$s">%1$s</a>', 'wp-job-manager' ), $apply->email, '?subject=' . rawurlencode( $apply->subject ) ) . '</p>';

			break;
			case 'url' :
				echo '<p>' . sprintf( __( 'To apply for this job please visit the following URL: <a href="%1$s">%1$s →</a>', 'wp-job-manager' ), $apply->url ) . '</p>';
			break;
		}

	echo do_shortcode( '[gravityform id="' . get_option( 'job_manager_gravity_form' ) . '" title="false" ajax="true"]' );

	?>

</div>

Essentially I’ve removed the “Apply with webmail” code from the main plugin file, and also removed

if ( class_exists( 'Astoundify_Job_Manager_Apply' ) ) :

from the provided ‘Nothing happening’ code (which seemed to be breaking the theme when it was included in full)

Now the gravity form can be submitted to the admin email in the usual way, plus any given parameters will be stored in the Gravity form “Entries” area too.

Might not be the best way of doing it, but it might help someone out!
