Erro ao dar logout

depois q por uma inspiração divina consegui trocar o idioma de inglês para português, fechei as janelas sem me deslogar e reabi tentei me logar e nada nem mudava de tela, digitei direto o blog e depois cliquei no edit e continuava logada. Verifiquei que o tema que instalei estava ok. Então quando tentei dar logout amareceu esta mensagem.
