I don’t know where the contact.css and contact.php come from, as all of my working contact pages have only the two index files. Maybe try deleting them off the server.
Deleted those files and still no success.
Hi @gregs
Can you provide a link to your Contact page?
The error seems to indicate you aren’t using the correct SMTP details in the form settings.
Did you ask Siteground to give you the SMTP details you should be using?
I have inquired via the Siteground AI Assistant and followed the instructions as shown:
If your form plugin supports SMTP, use:
-
SMTP Host:
mail.siewertdesign.com -
Authentication: On
-
Username: full email address
-
Password: that mailbox password
-
Encryption: TLS/STARTTLS
-
Port: 587
-
Fallback: SSL on 465
Maybe try talking to a human? They’d be able to check their mail logs to see why the form isn’t sending.
Here is Siteground’s help page on SMTP. According to that article, they suggest using SSL (Port 465) as the primary.
Yes, I have tried both TLS and SSL. Unfortunately, finding a human to talk to is extremely difficult.
Not with our hosting. 
Ha, ha!
I got it sorted through the Siteground Chat assistance.
My Site password is different than the email. 
Ugg.
In the end, I used Port 587 with TLS.
Works great now!
