Problem installing a template

I encountered various problems with the installation of the Newspaper - News & WooCommerce WordPress Theme template. the support team advised me to return the wp-config file to its original state in order to use the preset sites. Not having the skills, I ask for help with this operation. I attach the message with the directions below.

Hello,
The theme is now activated - https://i.imgur.com/KBgLxF1.png but it can not work correctly, and I further investigate this and it looks that you have some custom changes in the wordpress files like wp-config.php - https://i.imgur.com/yRtVDd1.png you should use the default settings from wordpress files so you can have access to cloud templates.
Thank you!
Calin

Salve,
ha provato a sbloccare le connessioni server to server da Impostazioni->Server to server?
Una volta sbloccate dovrà attendere 30 minuti perché lo sblocco abbia effetto.
