can’t increase a memory limit- 500 error only admin area

Please contact your host for specifics on making this work on their system.

Hello,

I contact my hosting before request your support.
The hosting open a memory limit 512m and I try to edit a wp-cofig but not working.
So I request your advised.
I don’t understand why my WP can’t increase a memory limit.

Thank you.

Have you also tried increasing memory in php.ini and .htaccess?

https://docs.woocommerce.com/document/increasing-the-wordpress-memory-limit/

Where do you see a memory limit of 64M?

I will try to increase memory in php.ini and .htaccess again.
I checked my memory limit by WP-Memory-Usage plugin.
And I compare it with phpinfo that my admin area show a memory limit=64m. but phpinfo show a memory limit of hosting=512m.
I consult with my hosting but the cause of problem not effect from hosting.

Thank you.

I try to do everything, increase memory in php.ini , wp-config, default-constants.php.
But still not working.
Can you help to find solution to solve this issue?

Thank you,

Do not touch default-constants.php.

Please show your wp-config.php file (but XXXX out all the passwords and secret keys).

Move the memory related lines above the line that says “stop editing”.

I move it follow your suggestion but not working.
The memory limit still has 64m.
Please see my screenshots of wp-config.php https://ibb.co/m1fipk
and my wp admin.
https://ibb.co/jnxUUk

what’s putting that line at the bottom of your admin screen? It’s not part of wordpress core.

I did not put or modify anything.
I just show a current of memory limit to you.
I used a Server IP & Memory Usage Display plugin that it display a memory limit in footer of admin.

Have you checked that there’s not .htaccess file in …/wp-admin/

Also try a php.ini file in your site’s root.

I try it but still not working.

I had more wordpress websites on same hosting but not found the memory limit issue.
And I try to replace WPv.4.8 again but not working, deactive all plugins and active one by one but not working too.
