Login to your Cpanel , Than go to “file manager” open “public HTML” Edit the code of “config.php”
use this code “define(‘WP_MEMORY_LIMIT’, ’64M’);”
#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
#3. Try adding this line to your wp-config.php file:
Increasing memory allocated to PHP
#4. Talk to your hosting company.
These days, even 128MB can be “tight” as plugins, themes and WordPress itself keep growing.
