Try re-uploading fresh WordPress files.
then it will lost Database;
tell me which files I should upload
Try:
– switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
– running the upgrade manually via wp-admin/upgrade.php
