Actually, similarly to another post : I found that the quotation marks around the hidden field attribute were wrong. It’s still not working though. My apache2 logs show :
[Tue Jan 24 17:28:08.461334 2017] [:error] [pid 16336] [client 208.xxx.xxx.xxx] PHP Notice: Undefined index: i in /var/www/sendy/subscribe.php on line 129
I have the same problem:
[tssendy listID "162"]
[hidden ts_sendy_hidden “true”]
<label> Your Name (required)
[text* your-name] </label>
<label> Your Email (required)
[email* your-email] </label>
[submit "Send"]
It sends me an email via the Contact Form 7 settings, but the subscription never appears at the sendy end.
I’ve added the Sendy API Key and installation URL to the default settings, and it should skip sending the mail, but doesn’t – which makes me think something with the plugin isn’t working will with WP 4.7.1’s plugin registration or shortcode?
