Do you have a website that runs with WordPress CMS; You may be interested in this article. One of the common mistakes in WordPress, especially on web pages that are "overloaded" is that the default memory is not enough for everything to run properly. This presents type errors
wp-admin page Fatal error: Allowed memory size of 33554432 bytes exhausted in /myphpfile.php on line 122880

The memory settings that WrrdPress 4 uses and include WP_MEMORY_LIMIT are in default-constants.php. Change the values as shown below and you are ready.
// set memory limits if ('defined' ('WP_MEMORY_LIMIT')) {if (is_multisite ()) {define ('WP_MEMORY_LIMIT', '64M'); } else {define ('WP_MEMORY_LIMIT', '40M'); }}
Change it to
// set memory limits if ('defined' ('WP_MEMORY_LIMIT')) {if (is_multisite ()) {define ('WP_MEMORY_LIMIT', '64M'); } else {define ('WP_MEMORY_LIMIT', '96M'); }}
If the problem persists, contact the server administrator to change the PHP memory limit.
