display greek characters like question ???? after update

    Hello,

    after update wordpress from 2.0.4 to 3.3.1 the site displays greek characters like question marks ????? in the old posts (content and title), as you can see at http://www.elliniko-fenomeno.gr . The strange think is that in the database, the greek characters displayed correctly, when i change the charset of DB and wp_post table from greek_general_ci to utf8 and collation to utf8_general_ci. In the wp-config.php there is no define(‘DB_CHARSET’, ‘utf8’) and define(‘DB_COLLATE’, ”). When i try to add them, the old post fixed, the new turn ???? but the worse is that i can’t access to wp-admin(you do not have sufficient permissions to access this page).

    Any help please?

    Did you try to upgrade to 3.3.1 in a single step? Did you make a pre-upgrade database backup?

    Did you check the site after each upgrade step? Did you backup the database after each successful upgrade step?

    Yes the problem begin from the first upgade step. I thought maybe fixed when finished to 3.3.1. No, i didn’t backup after each upgade.

    In that case, I’d suggest re-installing WordPress 2.0.4 and restoring your database backup. Then just carry out the first upgrade and see what happens.

    I think will happened as in the end. The problem was th db charset as wasn’t utf8 but greek_general_ci. The re-installing wordpress 2.0.4 is the one way i looking if there is another solution to the problem.

    Fix found. I converting database character sets in wp_posts table from utf8 to latin1. Strange!! The sql `alter table wp_posts change post_content post_content LONGTEXT CHARACTER SET utf8;
    alter table wp_posts change post_content post_content LONGBLOB;
    alter table wp_posts change post_content post_content LONGTEXT CHARACTER SET latin1;` Now everything is ok.
