 * Hello there,
 * It seems like there is a plugin conflict. Fluent SMTP overrides the default wp_mail
   function so if any other plugin uses this option then it could create a conflict.
   I would recommend you to temporarily disable all the plugins except Fluent SMTP
   and check if the issue is resolved. If so, kindly reactivate the plugins one 
   by one and see which one is conflicting.
 * Thank you
