Send your wordpress file again and click “overwrite” while sending then retry.
You may restrict accessing to admin panel by using .htaccess file based on IP address.
Like:
Deny from all
Allow youripaddress
However if your ip address is dynamic.This method will cause problems.
Or
May I find some plugin or hack for wordpress php files that publish comment or hold it for moderation according to comment author name.
Either of them will solve my problem.
