Test Email throws PHP Errors: Class SMTP Not Found
I'm just setting up WordPress to run on Ubuntu 16.04 and had the following error message popup when I tried to send a test email (through my gmail account) from EASY WP SMTP:
( ! ) Fatal error: Uncaught Error: Class 'SMTP' not found in /usr/share/php/libphp-phpmailer/class.phpmailer.php on line 1446 ( ! ) Error: Class 'SMTP' not found in /usr/share/php/libphp-phpmailer/class.phpmailer.php on line 1446 Call Stack
I checked /usr/share/php/libphp-phpmailer/ and there was definitely a class.smtp.php in there, so I have no idea why this error is occurred. I decided to just include the class.smtp.php in the class.phpmailer.php file by adding this line to /usr/share/php/libphp-phpmailer/class.phpmailer.php and it fixed the issue:
I'm a novice PHP user, and brand new to WordPress, so can anyone explain why this issue occurred in the first place? Why can class.phpmailer.php not find class.smtp.php if they are both in the same package and directory? Why is the include statement needed?
