Hello, try copying and pasting this command to restore config.json. Is this a solution?
cp /www/server/panel/config/config.json /www/server/panel/config/config.json_bak
echo '{"product": "Linux panel", "setup_path": "/www/server", "openlitespeed_path": "/usr/local", "language": "English", "title": "aaPanel Linux panel", "brand": "aaPanel", "root_path": "/www", "template": "default", "logs_path": "/www/wwwlogs", "home": "https://www.aapanel.com", "recycle_bin": true}' > /www/server/panel/config/config.json
bt restart
