Hi, we needed to upgrade the php version of our instance, so we create a new wordpress multisite instance on php 7.4.X.

there are some issues, and we dont know how to fix. we would like to get some help in this.
uploading a plugin gives this: The uploaded file could not be moved to wp-content/uploads/sites/2.
a check on the instance says this: Your instance has little available RAM memory.
also this message came up: 28-Sep-2021 09:31:55] ERROR: fork() failed: Cannot allocate memory (12)

This error  indicates there is a problem with the memory limit in PHP. Please 
check the following guide to increase the number of PHP-FPM child processes:

can we get some help to fix this?

Hello @peter2,

the mentioned memory.conf in this file refers to this file:

; Bitnami memory configuration for PHP-FPM
; Note: This will be modified on server size changes


Hello @peter2,

It depends on your site’s requirements. This guide may help (even though it is focused on nginx):

Let me share with you this previous answer.
