I think the database has something to do with it. There are sql error when viewing the tables. I double check it again. I can post but I just can’t create categories and tags.
Actually there are no plugins installed yet. And I’m currently using the default theme. I reinstalled the wordpress and used new database but still won’t work. It works fine in my local computer.
