I installed the plugin today. Everything is working okay except the sending mails part. When I try to send a test mail, this error shows up:
Last test failed with error “include(): Failed opening ‘/home/amnbh/public_html/wp-content/advanced-cache.php’ for inclusion (include_path=’.:/opt/alt/php70/usr/share/pear’)”.
Hi, that is not connected with the mailing. First, you have the caching enabled in your wp-config.php but you’re missing the advanced-cache file. If you’re not using a cache plugin, you should disable the caching in wp-config.php. Then check in that file if you’re running in debug mode, setting the constant wp_debug to false.
Then run a mailing test from the status panel of Newsletter.
