# User Meta database corruption

 *  Resolved [3Lancer](https://wordpress.org/support/users/3lancer/)
 * (@3lancer)
 * [7 years, 7 months ago](https://wordpress.org/support/topic/user-meta-database-corruption/)
 * I ran “Optimize Database after Deleting Revisions” version 4.6.3 upon a development
   server WordPress website and it’s gone destroying the User_Meta table of the 
   database. Not allowing any logins, even admin anymore. Haven’t had any issues
   from previous versions, till now.
 * Under the PHPMyAdmin, the table wouldn’t open and was marked as ‘Crashed’, while
   previous recovery failed.
 * I had to add under WpConfig.php
 * define(‘WP_ALLOW_REPAIR’, true);
 * Then run the tool to recover it: /wp-admin/maint/repair.php
 * Might just be an once off for me and this server, but just reporting it here 
   in case there’s an issue in the 4.6.3 build or others have similar problems. 
   Just remember it’s always best to make backups of your server/database content
   too (for any major updates or database changes, not just this tool).
 * Hope that can helps others out if ever running into this issue.

 * Hey 3Lancer,
 * It probably was a hickup of your system, because there are no other reports of
   this issue.
 * But, thanks for sharing!
