The Joomla email setting works perfectly, but when I use in Form Maker, it won't send email to administrator and user.
How to fix this?

Hi Sekolah,

Thanks for letting us know about the issue.

As it works properly, so please give us temporary administrator access to your website. You can send the login information using the contact form on this page. Our development team will make the changes as soon as possible.

Also make sure to indicate the link to this forum thread in your message.
Thanks! Have a wonderful day!
