I am getting a critical error when trying to do the following:-
1) Create a new newsletter using RAW HTML
2) Click on Test
3) The next screen loads with this error:
There has been a critical error on this website. Please check your site admin email inbox for instructions.
The email notification I received from WordPress was with this error message:-
Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.
In this case, WordPress caught an error with one of your plugins, Newsletter – Amazon SES.
An error of type E_COMPILE_ERROR was caused in line 604 of the file /…/wp-content/plugins/newsletter-amazon/plugin.php. Error message: require_once(): Failed opening required ‘/…/wp-content/plugins/newsletter/includes/PHPMailerLoader.php’ (include_path=’.:/opt/alt/php74/usr/share/pear’)
I am using Amazon SES Version 1.3.8. I have not been able to update to the latest version as my license has already expired. So does this mean I will not be able to use the Amazon SES extension anymore? I thought it would at least be backward compatible.
