WordPress WP_MEMORY_LIMIT is set to <?php echo $memory ?> megabyte but your PHP setting could allow more than that.
Anyway we suggest to set the value to at least 64M.
<a href="https://www.thenewsletterplugin.com/documentation/status-panel#status-memory" target="_blank">Read more</a>.
<?php if ($memory < 64) { ?>
This value is too low you should increase it adding <code>define('WP_MEMORY_LIMIT', '64M');</code> to your <code>wp-config.php</code>.
<a href="https://www.thenewsletterplugin.com/documentation/status-panel#status-memory" target="_blank">Read more</a>.
<?php } else if ($memory < 128) { ?>
The value should be fine, it depends on how many plugins you're running and how many resource are required by your theme.
Blank pages may happen with low memory problems. Eventually increase it adding <code>define('WP_MEMORY_LIMIT', '128M');</code>
to your <code>wp-config.php</code>.
