 * The database error is saying that your WordPress database is missing field _comment\
   _date\_gmt_ in table _wp\_comments_, which leads me to suspect that you either
   had problems installing WP, recently upgraded to a newer version of WP (and had
   problems) or activated some plugin that isn’t working correctly.
