Conflict with Gmail smtp-plugin

[dolf h]

First of all I wish to thank you for this wonderful Plugin. For the correct settlement of the e-mailtraffic from my website I recently had to install the Gmail-smtp plugin, because I use Gmail. So all the mails sending from my website are now handled by Gmail. It works fine, but now there is a problem with the Newsletter-plugin. Subscribing on my home-page (https://www.grenspostadres.nl/nieuwsbrief) fails. The confirmation-e-mail is not send and I get a white screen. Deactivating the Gmail-smtp plugin clears the problem, but I have to use both plugins.
Any suggestions how to solve this problem?

Anyone a clue? Too complicated 😉 ?

Hi, a white screen usually means a fatal PHP error. Can you find your server error logs?

Hi Stefano, thank you for your reply.

Here is the result of my error-log:

2016-10-11 09:48:21 PHP Fatal error: Cannot redeclare class PHPMailer in D:\appdata\IIS\vhosts\grenspostadres.nl\httpdocs\wp-includes\class-phpmailer.php on line 28 php_error

Has this issue been solved? I encountered the same issue! This is a blocker for me to continue using this newsletter plugin.

My symptom is that if I go to Diagnostic from the newsletter Settings and send the test email, it works. But if I go to Status and send a test message, it failed with “Last test failed with error “SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting”. “

Hi, I also encounter a black screen when using Newsletter with the plugin “Gmail SMTP”. The problem is solved and I can send Newsletters to the test adresses when I deactivate Gmail SMTP and install “Easy WP SMTP” instead.

However I would prefer to use Gmail SMTP. Is this possible? Will this conflict be solved soon?

Thanks for this great newsletter plugin!
