I am using PHP's mail function to send mail from my website, this had been working until recently when I changed the content of the actual message.
I have tried changing the content back but the same thing happens.
I do actually recieve the message and I can see the message content when I view the original message header but the actual email looks blank.
This is how I am sending the emails:
$to = [customer_email];
$subject = [email_subject];
$message_header= [message_header];
$message_content= [message_content];
$message_footer = [message_footer ];
$uid = md5(uniqid(time()));
$headers = "From: support@domain.com" . "\r\n";
$headers .= "Reply-To: support@domain.com" . "\r\n";
$headers .= "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n";
$headers .= "Bcc: sales@domain.com" . "\r\n";
$message = "--".$uid."\r\n";
$message .= "Content-type:text/html; charset=UTF-8" . "\r\n";
$message .= $message_header.$message_content.$message_footer . "\r\n\r\n";
mail($to, $subject, $message, $headers);
Like I said, the message is being sent and received and not being marked as spam but just appears blank but the content can be seen in the message header.
The full message header is here with just the details such as the domain and email addresses changed:

I know there are tools like phpmailer but I want to figure this out so I understand what is happening. any help or suggestions with this would be greatly appreciated.
//-----EDIT-----//
So a bit more information:
I've a few different areas where emails are being sent from but the header and footer are always the same just the body of the email changes, hence why I have
$message .= $message_header.$message_content.$message_footer . "\r\n\r\n";I am also translating the message content variable using
gettext(https://www.gnu.org/software/gettext/). These are translating fine and I can see it fine in the message header of the blank email received.Like I said, I have a few emails being sent from our system, the ones with the issues are all coming from my admin subdirectory, however, I also have a components subdirectory which has a mailing list sign up component which is included indirectly (included in another included file) in my main directory and this works fine.
//-----EDIT2-----//
I kind of half resolved this by removing the following lines
$message = "--".$uid."\r\n";
$message .= "Content-type:text/html; charset=UTF-8" . "\r\n";
And by changing:
$headers .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n";
to:
$headers .= "Content-Type: text/html;charset=UTF-8" . "\r\n";
The reason I had this in the first place was because I had been adding an attachment previously.
$message .= $message_header.$message_content.$trustpilot_script.$message_footer . "\r\n\r\n";
// $message .= "--".$uid."\r\n";
// $message .= "Content-Type: application/octet-stream; name=\"".$file_name.".pdf\"\r\n";
// $message .= "Content-Transfer-Encoding: base64" . "\r\n";
// $message .= "Content-Disposition: attachment; filename=\"".$file_name.".pdf\"\r\n";
// $message .= $content."\r\n";
// $message .= "--".$uid."--";
mail($to, $subject, $message, $headers);
I just hadn't included the commented out section of code in my original question but is there a way to get this to be able to send attachments as well?
