After moving a functional WordPress website from single-server to multi-server, file upload no longer works.
What problem do you have with file uploading?
The problem is that the email arrive without the attached files.
I add a Bcc: with your personal address to send an email with a joint file and see the results.
In the form : [file cupl1 limit:8388608 filetypes:txt|doc|docm|pdf|jpg|gif|png|zip]
In Attachenent: [cupl1]
See Setting up mail
What email settings do you have in the Mail tab panel?
To protect personal data, hiding email addresses in the settings or replacing them with dummy addresses is strongly advised.
Can you please include screenshots of the Mail tab panel?
Thanks.
I will send you all the configuration screenshots to your personal address.
