Hello, Oleksandr,
1/ FTP access works, but the directory is empty – https://prnt.sc/kV__lej0vXeB Please check the destination folder of our user, or ask your hosting provider for help with this, we need access to your WP installation.
2/ Please contact your hosting provider and ask error log, let us know what errors are detected.
Thank you for your cooperation and we look forward to hearing from you soon.
Kind Regards,
