Hi thanks. I continued my whole story in other's post and no one answer me, so i start my own new post. Ok, the details below:
I did a upgrade to 2.2 by Fantastico last night, and all the Chinese turn into ????. However i read from other's blog, knowing that i need to change all the database's collation to utf8_general_c. I did that too, but it was not working. I found some says need to edit wp-config.php file, so i did and it was even worse.
I managed to return back to 2.1.3, and it was a mess. The support from my Host suggested me to remove wordpress and reinstall again. I did removed the 2.1.3 but not able to install the wordpress 2.2 as i can't install two wordpress in the same domain. (funny! I did removed the old installation right? and there is no wordpress installed in my Fantastico).
Anyway when i assess my blog, the page was blank and asked me to do the installation. So i follow the steps and manage to install the 2.1.3. back. Now, the Chinese text still unreadable and many other errors too. I can't use the 'manage' tool now, and i have two error messages:
Fatal error: Call to undefined function get_private_posts_cap_sql() in /home/clblogne/public_html/wp-admin/index.php on line 64
Fatal error: Call to undefined function _get_category_hierarchy() in /home/clblogne/public_html/wp-admin/admin-functions.php on line 771
Sorry for the long story and really hope to solve the problems!
