Encountering the “Allowed memory size exhausted” error in WordPress indicates the need to increase your PHP memory limit. This guide outlines methods to adjust the memory allocation, including editing wp-config.php, .htaccess, or php.ini files, ensuring your site runs smoothly as it grows.
Email delays may lead to server timeouts and inaccurate statistics. If you receive a notification, it could be temporary and may resolve itself. For recurring issues, consider increasing your server’s memory limit or reducing the number of emails sent at once in newsletter settings.
If your email campaign isn’t sending, check key settings: verify newsletter delivery and cron job functionality, ensure server resources are adequate, and confirm you’ve selected recipients. Additionally, review any potential server issues or conflicts with third-party plugins. For assistance, contact your provider if you hit sending limits.
