 Well, in fact I did something previous to that, because I had a complete
 blank login page prior to the blocked cookies issue.

 I had a *clean* downloaded backup copy of my whole WP folder (e.g. WP1)
 which I uploaded to a new folder I just created for that (e.g. WP2). When
 I browsed to the backed up login file on this new folder (WP2), the login
 sent me to the first folder (WP1, as so it is defined in the wp-config.php
 to look at the -non modified- MySQL data-base ) and the error message was
 gone, although I had to reset my password, as mentioned in my first post.

 So hopefully you have a backup copy to try to play with.

 BTW if you look at the wp-login.php file, there it states the following
 regarding the blocked cookies error message.


 {{{
         // If the user was redirected to a secure login form from a non-
 secure admin page, and secure login is required but secure admin is not,
 then don't use a secure
         // cookie and redirect back to the referring non-secure admin
 page. This allows logins to always be POSTed over SSL while allowing the
 user to choose visiting
         // the admin via http or https.

         $user = wp_signon( '', $secure_cookie );

         if ( empty( $_COOKIE[ LOGGED_IN_COOKIE ] ) ) {
                 if ( headers_sent() ) {
                         $user = new WP_Error( 'test_cookie', sprintf( __(
 '<strong>ERROR</strong>: Cookies are blocked due to unexpected output. For
 help, please see <a href="%1$s">this documentation</a> or try the <a
 href="%2$s">support forums</a>.' ),
                                 __( 'http://codex.wordpress.org/Cookies'
 ), __( 'https://wordpress.org/support/' ) ) );
                 } elseif ( isset( $_POST['testcookie'] ) && empty(
 $_COOKIE[ TEST_COOKIE ] ) ) {
                         // If cookies are disabled we can't log in even
 with a valid user+pass
                         $user = new WP_Error( 'test_cookie', sprintf( __(
 '<strong>ERROR</strong>: Cookies are blocked or not supported by your
 browser. You must <a href="%s">enable cookies</a> to use WordPress.' ),
                                 __( 'http://codex.wordpress.org/Cookies' )
 ) );
                 }

 }}}


 Does it say something to you?
