There was an error while creating a staging site through CyberPanel. There was a problem that when the master site have a different $table_prefix value in wp-config.php it was not working.
To rectify this problem. I’ve first fetched the table_prefix from master site here.
Then after the wp config file for staging site is configured, I’ve used wp config command to set this table prefix here.
On your CyberPanel installation this file is available at /usr/local/CyberCP/websiteFunctions/StagingSetup.py
So if you are a developer, you can use any editor to make improvements to this file and then run systemctl restart lscpd to apply those changes to take affect.
