Contact form 7 not sending attachment with email after latest update

I have the same problem: everything works fine, but the email attachment is not attached in either the mail to me or the one to the sender, although the message appears that sending worked.

Yes, I put the file in the “E-mail” tab in both mails with the e-mail tag [file-687] given above in the “File attachments” field.
There is also a folder wpcf7_uploads on the server – I gave it public write permission (766).
I have also tried it with a second file and have it displayed in both mails as well (this works – the file name is displayed) and also added both mail tags [file-687][file-173] in the File Attachments field. Nevertheless the mails have no attachment.

Thanks for any tips that help here!

Great that you found a solution! 😀
I searched for the function file on the server and found 4 files with “function” in the name inside the plugin folder, but none contains “wpcf7_ajax_json_echo”. Where exactly do I have to remove the hook?
Thanks in advance for your help!

Thanks for the quick reply!
I searched all “function” files in “contact-form-7” folder for “wpcf7_ajax_json_echo” but found nothing.
I have the “functions.php” file under “contact-form-7 > includes”.
Even if I search the terms individually, neither “ajax”, nor “json” nor “echo” is found in this file.

I have a multilanguage site and amazingly the contact form including attachment works on the English page (same plugins and settings). Only on the German one the attachment doesn’t work. I have nevertheless deactivated various plugins testwise, but unfortunately without success. Thanks for the tip anyway!

Yes, I have. 😉👍
