This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them. * Thread Starter [rikypg](https://wordpress.org/support/users/rikypg/) * (@rikypg) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-41-upgrade-database-problem/#post-5784653) * I have already try toupload fresh files, but the problem still present. * [shamratdewan](https://wordpress.org/support/users/shamratdewan/) * (@shamratdewan) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-41-upgrade-database-problem/#post-5784655) * i think its you hosting not letting DB to update. check your php mysql version, repair/optimise database, reset htaccess file then try again… if not speak to your hosting * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-41-upgrade-database-problem/#post-5784656) * What version were you updating from? * Thread Starter [rikypg](https://wordpress.org/support/users/rikypg/) * (@rikypg) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-41-upgrade-database-problem/#post-5784665) * The update is from 4.0 , I hope…. the php version is 5.4.35 Mysql 5.5.40 I have already try to repair and optimize but nothing change. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-41-upgrade-database-problem/#post-5784666) * Ok, it could be one of your plugins, or you theme functions, conflicting. * Try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)( no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause. * If that does not resolve the issue, access your server via [FTP or SFTP](https://codex.wordpress.org/FTP_Clients), navigate to `/wp-content/themes/` and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule- out a theme-specific issue (theme functions can interfere like plugins). * Thread Starter [rikypg](https://wordpress.org/support/users/rikypg/) * (@rikypg) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-41-upgrade-database-problem/#post-5784668) * Give me this message at link [http://site.it/wp-admin/upgrade.php?step=1&backto=](http://site.it/wp-admin/upgrade.php?step=1&backto=) * NOT FOUND * You tried going to [http://site.it/wp-admin/upgrade.php?step=1&backto=](http://site.it/wp-admin/upgrade.php?step=1&backto=), and it doesn’t exist.
