 * When I set up a website for my wife to do a blog, somehow I managed to create
   3 databases. How can I combine these into one?
 * When I update WordPress all three update, so I presume they are all used.
 * I am trying to tidy up the site, so would like to only have one database to deal
   with.
 * Thanks
 * Bill

 * Sorry, that sounds a bit odd to hear all three database get updated.
    Because
   If you know in the config file you define only single database for site.

 * Deepvyas,
    Well WP Manager by Softaculous shows three installs and if I check
   the database settings they are different numbers.
 * So are two of the DBs just on the system, but not being used by the website?

 * -are you able to see the database settings in your website’s wp-config.php file?
   does the database name match one of the databases in your webhosting account?
   -
   do the other 2 databases have any content in the tables that corresponds to your
   active website? -if you are not sure how to find WP-config.php file, please contact
   your webhost support for specific instructions. **IMPORTANT: before deleting 
   or combining any database(s) — be sure to create and save a complete backup copy
   of the all database(s).**

 * Lisa,
 * Thanks.
    wp-config shows: /** MySQL database username */ define(‘DB_USER’, ‘bn9couk_wp124’);
 * wp124 runs right through from 2013 to today.
 * Other two only 2013-2015.
    So as wp-config doesn’t mention other two databases
   I presume they can go.
 * Even with a complete backup of all DBs, still not sure easiest way to remove 
   the surplus databases.

 * On your hosting login goto MySQL Databases and delete unused one from the list.
