memory - WP_MEMORY_LIMIT didn't work in wp-config, only within default-constants.php

i have already searched here and tried a lot of things, but my problem still is "alive"

It is possible to set WP_MEMORY_LIMIT within the default-constants.php and this works fine, but every time I update wordpress I have to make this setting again. So my wp-config.php does not overwrite the setting in the default-config.php.

The wp-config-file was created directly from wordpress automatically.

I have checked this thread, my setting for WP_MEMEORY_LIMIT is directly below WP_DEBUG and before ABSPATH is defined.

$table_prefix  = 'hp365_01_';

define('WP_DEBUG', false);
define(‘WP_MEMORY_LIMIT’, ’128M’);

/* That's all, stop editing! Happy blogging. */

Maybe somebody has the same problem ?

Your code appears to be using he incorrect quote characters. You have ’ instead of '. This can happen if you copy it from a site where the quotes have been converted to ‘fancy quotes’ by the publishing platform but the author didn’t catch it.

So replace

define(‘WP_MEMORY_LIMIT’, ’128M’);

With

define('WP_MEMORY_LIMIT', '128M');

I just had the same problem, thank you so much for the answer!! You just saved my website, I was facing http 500 error and started panicking.

The only thing is I never edited the wp config file, the wrong quote characters appeared by themselves, my website was up and running since 2021 until today, how can it be possible?
