Allowed memory size of 33554432 bytes exhausted (tried to allocate 43148176 bytes) in php

Answer 1

ini_set('memory_limit', '-1');

Answer 2

Write

ini_set('memory_limit', '-1');

in your index.php at the top after opening of php tag

Answer 3

Here are two simple methods to increase the limit on shared hosting:

1. If you have access to your PHP.ini file, change the line in PHP.ini If your line shows 32M try 64M: memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

2. If you don't have access to PHP.ini try adding this to an .htaccess file: php_value memory_limit 64M

Answer 4

I was receiving the same error message after switching to a new theme in Wordpress. PHP was running version 5.3 so I switched to 7.2. That fixed the issue.

Answer 5

Run this command in your Magento root directory php -d memory_limit=4G bin/magento

Answer 6

I was also having the same problem, looked for phpinfo.ini, php.ini or .htaccess files to no avail. Finally I have looked at some php files, opened them and checked the codes inside for memory. Finally this solution was what I come out with and it worked for me. I was using wordpress, so this solution might only work for wordpress memory size limit problem. My solution, open default-constants.php file in /public_html/wp-includes folder. Open that file with code editor, and find memory settings under wp_initial_constants scope, or just Ctrl+F it to find the word "memory". There you will come over WP_MEMORY_LIMIT and WP_MAX_MEMORY_LIMIT. Just increase it, it was 64 MB in my case, I increased it to 128 MB and then to 200 MB.

// Define memory limits.
if ( ! defined( 'WP_MEMORY_LIMIT' ) ) {
    if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
        define( 'WP_MEMORY_LIMIT', $current_limit );
    } elseif ( is_multisite() ) {
        define( 'WP_MEMORY_LIMIT', '200M' );
    } else {
        define( 'WP_MEMORY_LIMIT', '128M' );
    }
}

if ( ! defined( 'WP_MAX_MEMORY_LIMIT' ) ) {
    if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
        define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
    } elseif ( -1 === $current_limit_int || $current_limit_int > 268435456 /* = 256M */ ) {
        define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
    } else {
        define( 'WP_MAX_MEMORY_LIMIT', '256M' );
    }
}

Btw, please don't do the following code, because that's bad practice:

ini_set('memory_limit', '-1');
