I found a bug

Hi all,

I’m using ‘Gmail SMTP plug-in’ version 1.1.9.
I have found a bug, due to this bug, emails cannot be sent.

Error logs:

2020-07-29 02:46:52 Auth method requested: XOAUTH2
2020-07-29 02:46:52 Auth methods available on the server: LOGIN,PLAIN,XOAUTH2,PLAIN-CLIENTTOKEN,OAUTHBEARER,XOAUTH

Server info:

OS: Linux xxxxxxxxxxx.com 3.10.0-1127.10.1.el7.x86_64 #1 SMP Wed Jun 3 14:28:03 UTC 2020 x86_64
PHP version: 7.4.8
WordPress version: 5.4.2
WordPress multisite: No
openssl: Available
allow_url_fopen: Enabled

cURL Version: 7.70.0, OpenSSL/1.0.2k-fips

The error ONLY occurs when the user has the plug-in ‘WooCommerce PDF Invoices & Packing Slips version 2.5.3’ activated in combination with PHP-version 7.3 or higher.

So, if the user downgrades the PHP-version to 7.2 OR deactivate the plug-in ‘WooCommerce PDF Invoices & Packing Slips’ then the error/bug is solved.

Of course this is not a sustainable solution. Either the author of ‘WP Gmail SMTP’ or ‘WooCommerce PDF Invoices & Packing Slips’ should fix the bug.

Thanks in advance!

Cheers,
