Not working since 4.6

I am having the same issue. No emails go out since latest update…I am seeing the messages in Flamingo but neither myself or submitter are receiving emails.
Strangely enough, when I try to test it, I do get an email…haven’t been able to figure out if it is specific to a certain browser or device yet.

I noticed some issues with others plugins but since I did not use jet pack I disable it then found everything worked fine. I have 4.6 and contact 7 too and it’s work fine now.
And also try to disable Clef plugins “if you have it” and try

Same problem here.

We are having the same issue here

Same problem here with Contact Form 7 and WP 4.6.

I find solution on other forum to wait future update of the plugin :

//////////

I changed the wp_mail() function to mail() and removed $attachments. This is working for my setup with contact-form-7 4.5 and wordpress 4.6. Obviously without attachments.

see /wp-content/plugins/contact-form-7/includes/mail.php (Line 85)

old:
return wp_mail( $recipient, $subject, $body, $headers, $attachments );

new:
return mail( $recipient, $subject, $body, $headers );

thanks very much for the solution, that works great pending an update from the vendor.

Hello,

I went to the same folder that was described and also made the suggested changes. I am still not able to send email via the contact form on the website I am working on. Is there anyhwere else I can make adjustments? Am I missing something?

Thanks for helping in advance.

Hi, are you sure change return wp_mail in return mail ?
So, you can try to use ‘WP Mail SMTP’plugin.

Any update from the plugin author? I’m holding off updating WordPress core to version 4.6 on 17 of our client sites because they are using this plugin. I don’t want to have to hack the plugin to fix the issue. I’m just looking for an official update as to when we might expect an updated version of the plugin with the fix. Thanks!
