 * First, the readme is lacking in terms of upgrading .71 to .72. I gathered that
   it involved replacing all the files, editing wp-config.php and running the upgrade
   page…all was well until:
    [Table ‘foranewliberty_com.wp_linkcategories’ doesn’t
   exist] Admittedly, I don’t know the names of my tables, but I do know that they
   are what WP made them when I intially installed this wonderful program 4 months
   ago…any ideas? foranewliberty_com is the name of my db…apparently, the upgrade
   is prefixing all the queries with this name and the db doesn’t like it…how do
   I alter it so it just asks for “wp_<insert name>”? Thanks!

 * Most probably your tables are named with a prefixing b2_…, but the default configuration
   of 0.72 is assuming wp_… as prefix. Change that accordingly in the wp_config.
   php and it should work (I guess).

 * it is worth looking at your db using phpmyadmin to see the table structure … 
   in fact you can export a copy of your table using it for backup purposes every
   once in a while so that if something breaks in the mysql setup you aren’t up 
   a creek without a paddle
    for those that have never used it, it is an incredible
   tool … will even help write your php and mysql queries: [http://www.phpmyadmin.net/home_page/](http://www.phpmyadmin.net/home_page/)
