 * Hello I have had to use the Version 1.2.28
 * Why? Because the latest version still has the PHP error and the website stops
   sending emails completely when I update. Whereas 1.2.28 seems to have worked 
   until now.
 * I have 2 websites:
 * First website will now not Sync my contacts now when I hit apply and nothing 
   happens.
 * The other website I get the following message when I log in and I tried deactivating
   plugins still happens: “You cannot to use Sendinblue SMTP now because wp_mail
   has been declared by another process or plugin.”
 * However, nothing on either of these plugins has changed recently. Maybe only 
   WordPress Version.
