CRITIC ERROR

Hello, fellow colleagues,

Really in need of your massive help!

Trying to set up a staging ambient for a massive website I’ve done it manually and tried to do it by the book. I’m kinda new to all that and excuse me if I’m saying something wrong.

Step by step:
Backup > create the folder > Copied files there > Created a DB > Added same user from the main one > exported production DB > imported to new DB > edited options.php table and the wp-config.php file
but then…

1 – Uncaught Error: Call to undefined function Automattic\Jetpack\Autoloader\jp312e754a5f04819d41fea12273f49210\set_up_autoloader() in /home/artelusa/public_html/staging/wp-content/plugins/woocommerce/vendor/autoload_packages.php:14 Stack trace: #0 /home/artelusa/public_html/staging/wp-content/plugins/woocommerce/src/Autoloader.php(37): require() #1 /home/artelusa/public_html/staging/wp-content/plugins/woocommerce/woocommerce.php(27): Automattic\WooCommerce\Autoloader::init() #2 /home/artelusa/public_html/staging/wp-settings.php(377): include_once(‘/home/artelusa/…’) #3 /home/artelusa/public_html/staging/wp-config.php(104): require_once(‘/home/artelusa/…’) #4 /home/artelusa/public_html/staging/wp-load.php(37): require_once(‘/home/artelusa/…’) #5 /home/artelusa/public_html/staging/wp-admin/admin.php(34): require_once(‘/home/artelusa/…’) #6 /home/artelusa/public_html/staging/wp-admin/index.php(10): require_once(‘/home/artelusa/…’) #7 {main} thrown – /home/artelusa/public_html/staging/wp-content/plugins/woocommerce/vendor/autoload_packages.php – 14
