Hello, Eduardo
Please provide temporary wp-admin access.
Also, provide screenhots of untranslated strings.
To provide wp-admin access, you can create a new user account with administrator role via the Dashboard, and provide us with the username and password via the Private Content area.
You can use Lightshot screenshot or Gyazo tool to make screenshots and share the links here, or you can use a file sharing service such as WeTransfer https://wetransfer.com/
Kind Regards,
8theme team
