I do not have Formidable Pro and cannot get it because it costs money, but if the free version is based on the same codebase I can look into that. I just want to make sure I’m on the right track before I try. 🙂 Thanks for reporting the issue! * Thread Starter [boblmartens](https://wordpress.org/support/users/boblmartens/) * (@boblmartens) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-send-encrypted-email-to-array/#post-7102367) * Totally understand. I have a test instance I can get up and running and see if I can get it to work. I’ll report back soon. * Thread Starter [boblmartens](https://wordpress.org/support/users/boblmartens/) * (@boblmartens) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-send-encrypted-email-to-array/#post-7102381) * Same thing from a test site running 4.4.2 with the free version of Formidable and 0.3.0 of your plugin (since 0.4.0 threw me the syntax error that I started an issue on at GitHub). * `PHP Warning: trim() expects parameter 1 to be string, array given in /srv/www/ htdocs/wp-includes/class-wp-user.php on line 201, referer: http://blogs.mlc-wels. edu/bits-to-bytes/test-page/` * Thread Starter [boblmartens](https://wordpress.org/support/users/boblmartens/) * (@boblmartens) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-send-encrypted-email-to-array/#post-7102382) * Also, the email notification is sent, but it is not encrypted. * Plugin Author [Meitar](https://wordpress.org/support/users/meitar/) * (@meitar) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-send-encrypted-email-to-array/#post-7102387) * Cool, I will have a look ASAP. Can you add this issue to the GitHub tracker, too? * Thread Starter [boblmartens](https://wordpress.org/support/users/boblmartens/) * (@boblmartens) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-send-encrypted-email-to-array/#post-7102392) * I will do that. Thanks! * Plugin Author [Meitar](https://wordpress.org/support/users/meitar/) * (@meitar) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-send-encrypted-email-to-array/#post-7102446) * Thanks for adding this to the GitHub issue tracker; I will mark this “resolved” as it seems to be a bug and should be tracked there as such. Resolution will be to update to a later version of the plugin after I release an update.
