Title: Fatal error: Cannot redeclare require_wp_db Last modified: August 19, 2016 --- # Fatal error: Cannot redeclare require_wp_db * [ereaderguy](https://wordpress.org/support/users/ereaderguy/) * (@ereaderguy) * [15 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-require_wp_db/) * I tried to upgrade one of my blogs to 3.1 from 3.0.? (not sure of the specific number). Now all I get is this: * Fatal error: Cannot redeclare require_wp_db() (previously declared in /home/stephensmith/ libre.ereaderjournal.com/wp-includes/load.php:323) in /home/stephensmith/libre. ereaderjournal.com/wp-includes/functions.php on line 3090 * I searched the forum and found this post, which may be related: [http://wordpress.org/support/topic/wp-31-pg4wp-cannot-redeclare-class-wpdb?replies=1](http://wordpress.org/support/topic/wp-31-pg4wp-cannot-redeclare-class-wpdb?replies=1) * However, I do not understand the answer. What does it mean to re-implement the WP 3.1 require_wp_db() function? * Does this mean there’s a specific file that I need to download and rewrite (like in Notepad)? And does this indeed apply to the error I am getting? * Thanks for any help.

You may need to try logging into your site to get this to kick in fully. * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) by FTP or phpMyAdmin. * – re-running the upgrade manually. * Thread Starter [ereaderguy](https://wordpress.org/support/users/ereaderguy/) * (@ereaderguy) * [15 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-require_wp_db/#post-1944286) * Thanks esmi. * I assume that you meant that if I renamed my current theme’s folder to something else (anything else), that WP would default to Twenty Ten as the theme. Otherwise I am not sure how to make Twenty Ten my theme, since I cannot log in to wp-admin. So … I did rename my current theme’s folder. (The theme was Enterprise, so I named the folder enterprisebak.) * I also followed the instructions for resetting my plugins folder, up to the point where it said to log in to my wp-admin (which I cannot do). * These did not solve my problem, so now I will try the manual upgrade. I assume this means finding the WP 3.1 distribution file and using FTP to deploy it in my WP directory. Will my database with all my old content be protected if I do this? * Thanks again. * [WHAMI.ORG](https://wordpress.org/support/users/whamiorg/) * (@whamiorg) * [15 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-require_wp_db/#post-1944551) * I am having the same problem…however, I do not know how to do the manual upgrade& would like to know if my original content will be lost. * [WHAMI.ORG](https://wordpress.org/support/users/whamiorg/) * (@whamiorg) * [15 years, 1 month ago](https://wordpress.org/support/topic/fatal-error-cannot-redeclare-require_wp_db/#post-1944552) * HELP! During an upgrade…something drastically went wrong! I cannot login to my wordpress page & I keep getting errors as I try to tweak things to make the code work. I am more than willing to completely start over, without losing all of my “stuff” on my site. Can someone help me? I have tried to upgrade manually – but the only way I can do this is if I upload one file at a time. I use netfirms as my host. I have tried using FileZilla…but I do not know my “host name” to login. I am so beyond upset! I have spent a whole day working on this. WASTED a whole day working on this.
