When sending email invitations / reminders for a survey the text goes out as unformatted simple text, instead of using html formatting. I have enabled the ”Use HTML for participant emails” option in the survey settings, as described here: forums.limesurvey.org/forum/can-i-do-thi...-as-formatted-emails

But this solution did not work for me. Is this maybe a server configuration issue?

Thank you.

Seems there are more and more issue with this part .

Your LimeSUrvey version and buil number ?
Can you
1. Set HTML email as ON
2. Save (again) HTML template
to see if it fix the issue ?

Thank you for assistance. I tried again saving as you said above. I get the message "Email templates saved" and it all looks ok in the email template editing part. However, when I return to sending the invitations options in the participants menu the message appears as unformated text with html code (like <p> etc.).

My LimeSurvey ver is: 4.3.16+200915

Thanks!

Could you update to 4.3.21 ?
If yes : test again , if still broken : report the issue (i think it was already reparted and fixed, but don't remind the version).

Thanks. Will try to update and will test afterwards.
