Mails from UM miss content-type in headers

    The emails sent from Ultimate Member won’t work. When received gmail can’t read the HTML content. Instead the email is empty, except for a .txt file containing the HTML.
    I’m using WP Mail SMTP for mailing, and the test email from there is sent and readable. The main difference I can see in the headers is that the working mail from WP Mail SMTP has Content-Type: text/html; charset=UTF-8 while the not working mail from UM only has Content-Type: ; charset=UTF-8, but also Content-Transfer-Encoding: 8bit

    What can I do about this?

    Hi @punchlinern

    Did you turn on the Email HTML option in the WP Admin > Ultimate Member > General > Emails?

    Hello @champsupertramp, thanks for your quick reply!

    Yeah, I’ve tried with it both on and off. No difference.

    Hi @punchlinern

    Could you please tell me what UM Email templates are having this issue? Could you please paste the Raw email template here so we can investigate?

    Hi @champsupertramp, thanks again!

    It seams to be all templates, but here is the activation mail for instance:

    <div style="max-width: 560px; padding: 20px; background: #ffffff; border-radius: 5px; margin: 40px auto; font-family: Open Sans,Helvetica,Arial; font-size: 15px; color: #666;">
<div style="color: #444444; font-weight: normal;">
<div style="text-align: center; font-weight: 600; font-size: 26px; padding: 10px 0; border-bottom: solid 3px #eeeeee;">{site_name}</div>
<div style="clear: both;">?</div>
</div>
<div style="padding: 0 30px 30px 30px; border-bottom: 3px solid #eeeeee;">
<div style="padding: 30px 0; font-size: 24px; text-align: center; line-height: 40px;">Tack f?r att du har registrerat dig!<span style="display: block;">Tryck p? knappen nedan f?r att aktivera ditt konto.</span></div>
<div style="padding: 10px 0 50px 0; text-align: center;"><a style="background: #555555; color: #fff; padding: 12px 30px; text-decoration: none; border-radius: 3px; letter-spacing: 0.3px;" href="{account_activation_link}">Aktivera mitt konto</a></div>
<div style="padding: 15px; background: #eee; border-radius: 3px; text-align: center;">Beh?ver du hj?lp? <a style="color: #3ba1da; text-decoration: none;" href="mailto:{admin_email}">Kontakt oss</a>.</div>
</div>
<div style="color: #999; padding: 20px 30px;">
<div>Tack!</div>
<div><a style="color: #3ba1da; text-decoration: none;" href="{site_url}">{site_name}</a> teamet</div>
</div>
</div>

    This is what you’re asking for, right?

    Hi @punchlinern

    Have you tried deactivating other plugins and leaving UM and WP Mail SMTP activated?

    Let’s see if this is a plugin conflict issue.

    Hey @champsupertramp

    I’ve narrowed it down to a custom plugin we’ve built. I should have guessed. Do you have any idea what could cause this specific issue? What I should be looking for?

    (@punchlinern)

    I found it. It was a filter on wp_mail_content_type with a function that had been removed, so content type wasn’t returned.

    Thank you @champsupertramp for your assistance!
