hi, thank you for your reply.
in fact, renaming Wordfence plugin directory that error will disappear, but I still cannot login: when I put my (right) credentials and press Login the login screen would be simply reloaded without any error in console (F12).
in this scenario no message will be prompted, compared when Wordfence is active and after a login attempt I receive a wrong credential message.
maybe could be some other php files that Wordfence change outside plugin directory ?
thank you very much for your support.
