Emails not arriving

Hello,
I am using Universal email to cause an email thank you to be sent when a form is completed.
One of the three forms was sending the email but now none are working.
I am sending further details and some files.
Please see PM

/boats_Insert.php page doesn't have an email server behavior on it, so it wouldn't send an email.

the next page it goes to seems to be /boats_Insert_images_free.php. That page has two email server behaviors, but the first one has a redirect, so the second one wouldn't send.

The first one should be trying to send, but I see that the first and second one have different credentials for the email server. Perhaps that is the issue.

If you can't figure out why it isn't sending, then I'd suggest a premier support ticket so I can do screen sharing with you and debug it, and I can show you how to properly debug email issues moving forward. It isn't something I can necessarily spot in the code since the issue could be in the server, database, SMTP server settings, Spam filters, or even DNS settings.

Hello Ray
Sorry I have been away for a couple of weeks.

Last night I went into this site and a page was working correctly in accessing to the next correct page.
This morning it was trying to direct me to an incorrect page, the code was changed.

This is the working code
$InsertGoTo = "boat_insert_images_Free.php";
it was changed to
$InsertGoTo = "some other page, not sure which";

I wondered if you know of any likely cause of such an occurrence?
No other person has access.
Thanks for any help
John

Nothing should cause that. I really couldn't tell you how it got changed. It has to have been done by someone.
