(Still) Duplicate Mime Headers

Can you try this update:

Thank you for the reply. I already solved the problem by removing all lines with “MIME-Version: 1.0\r\n” in the file “quick-contact-form.php”. According to diff this is exactly what you did now in this update ??

Could you let me know if there are any other changes you made? Is there a git repository or another way to see a diff?

In any case, if this is the only change, then I think 6.20 can be released like this.

I’ve not made any other changes. I’ll get this update uploaded in the next couple of days when I have some free time.

Thank you very much!!
