Hi,
I found a bug in the frontend form.
If I add any external domain in the redirect parameter (e.g: https://www.google.com) of the shortcode, I'm redirected to the WordPress login page (wp-admin) after submission.
The redirect parameter only works with internal URLs.
But if I add the ajax="true" parameter to the shortcode, the redirection works just fine with external domains.
Example:
[mb_frontend_form post_fields="title,content" ajax="true" redirect="https://www.google.com"]
.
