Few of you might have faced this memory limit issue on your server and wordpress by which some of the features may behave improper

you can solve this issue very simply

let us take an case study

suppose your  server size limit is 1 Gb you can decide memory limit project wise , folder wise and wordpress level

To set memory limit in php project

to change go to

php.ini file and change in
memory_limit = “as per your desire” ;
To set memory limit in folder level

go to .htaccess file: and change
php_value memory_limit 256M or as per your requirement
To set memory limit in wordpress level:

Edit your wp-config.php file and enter something like:
define(‘WP_MEMORY_LIMIT’, ‘256M’);

to use this you must be careful about the hierarchy of your server memory

server memory

                      wordpress memory

if child memory is more then parents then it will give the error
