I updated WordPress 3 days ago. After updating I got blank pages, and could not even log in. Then I reinstalled WordPress from CP of my hosting company. The result was I got a new blog with none of my previous posts. Two new databases were created one of which is in the wp-config.php file. My backed up database files are in the FTP panel, but not in the database list. My uploads (images) are also in the FTP panel. I placed the problems before customer support of my hosting company. I got no specific replies, but only some stock replies. Will anyone help me by advising me what to do?
