Comments error

Hi guys,

when trying to post a comment on my wordpress I get this error:

Not Found
The requested URL /wp-comments-post.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Yet I have checked several times and the aforementioned file is present on the server. I tried downloading again and reuploading a new file to see if the file could be corrupted but still no change.

If anyone could help I’d be very greatful.

Kind regards,

Jonnie
