We have a client form that has 2 file upload field options. Both are limited to 10mb on file size. Whenever a user uses both fields, in the notification to our client the second file is corrupted. The email contains a link to the file on the server, and also attaches the file. If we click the links to the remote files, they work and we aren’t notified of file corruption. If we click the 2nd attachment, multiple email clients alert our client to a file corruption.
In my recent test, both files were 4.2mb in size. We are on Gravity Forms version 2.8.12. I do see a server error with a 502 Bad Gateway(we use WP Engine).
How can we prevent the file corruption via email?
