Not Increasing the WordPress Memory Limit

Hello!
I have edited wp-config.php and php.ini.

/etc/php/7.2/fpm/php.ini : memory_limit = 256M
wp-config.php :
define( ‘WP_MEMORY_LIMIT’, ’96M’ );
define( ‘WP_MAX_MEMORY_LIMIT’, ‘256M’ );

Still, increase the memory in the WP Memory Limit of the system status.

“40 MB/request – We recommend setting memory to at least 128MB. The theme is well tested with a 40MB/request limit, but if you are using multiple plugins that may not be enough. See: Increasing memory allocated to PHP. You can also check our guide here.”

What should I do ???

make sure you are using ‘ marks and not curly quote marks ‘

Thanks, but I copied and pasted the sample source.

I have exactly the same problem. Theme status not reflecting changes to php.ini file.
