Thank you for you help,
It help me one step. I removed htaccess file, deactivate and reactivate. Then try to save settings. Itheme now recognized that it is Nginx server but gave me error as he is trying to save the file to a path used on my old hosting.And it should use new path on my new hosting
(” The file path supplied in NGINX Conf File cannot be used as the parent directory cannot be created. The directory /home/zven12/public_html could not be created due to an unknown error. This could be due to a permissions issue.
The directory supplied in Path to Log Files cannot be used as a valid directory. The directory /home/zven12/public_html/wp-content/uploads/ithemes-security/logs could not be created due to an unknown error. This could be due to a permissions issue.
The settings could not be saved. Please correct the errors above and try again.”)
