There is a problem a simple user or a visitor can not comment on my posts. It gets this error:
Spam Free WordPress could not retrieve the password from the server. It may be necessary to do one, or all, of the following. Turn on the Old Password Fields option, turn off Nonce Security, or to turn on Generate Comment Form. Troubleshooting.
But all the settings are set as it is given above to set. ALso key is valid but still problem. How to solve it?
