Updated to v5.5 of Newsletter for Prestashop...Now fails when I try to send test email

[rgwhitaker]

I just updated the Newsletter for Prestashop module to v5.5 today.

 

I then tried to send a test email and it FAILED.

 

The error at the top of the page is:

 

exception 'Swift_ConnectionException' with message 'Authentication failed using username <email>' and password '********'' in <mysite>/public_html/tools/swift/Swift/Connection/SMTP.php:414 Stack trace: #0 <mysite>/public_html/tools/swift/Swift/Connection/SMTP.php(331): Swift_Connection_SMTP->runAuthenticators(<email>', '***', Object(Swift)) #1 <mysite>/public_html/tools/swift/Swift.php(264): Swift_Connection_SMTP->postConnect(Object(Swift)) #2 <mysite>/public_html/tools/swift/Swift.php(220): Swift->handshake(Object(Swift_Events_ResponseEvent)) #3 <mysite>/public_html/tools/swift/Swift.php(101): Swift->connect() #4 <mysite>/public_html/modules/newsletteradmin/classes/NewsMail.php(77): Swift->__construct(Object(Swift_Connection_SMTP), '<URL>') #5 <mysite>/public_html/modules/newsletteradmin/controllers/admin/AdminNewsletter.php(1116): NewsMail::Send(NULL, 'newsletter', 'Newsletter of S...', Array, '<email>', NULL, '[email protected]...', 'PRIMZIE', NULL, NULL, '<mysite>/p...', false, 1, NULL, NULL) #6 <mysite>/public_html/classes/controller/Controller.php(158): AdminNewsletterController->postProcess() #7 <mysite>/public_html/classes/Dispatcher.php(348): ControllerCore->run() #8 <mysite>/public_html/adminx0109a/index.php(53): DispatcherCore->dispatch() #9 {main}

 

Any ideas why this is occurring?

 

Thank you.
