PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'fmotors_fms.block_node_type' doesn't exist: This was working fine last night but when i login to my computer again I got this error now. What is this table {block_node_type} I cant find it in the database but it is in the drupal code in node.module. PLease help
If it was working last night, and now it doesn't and the table is missing, then the table has been deleted/renamed, or the database is partially corrupted. There isn't any other logical explanation.

As you rightly say that table is installed, unconditionally, by the node module upon installation of Drupal (see node_schema()).

If the table is really gone then your only option is to restore the DB from a backup; or if there was no data in that table, just manually create it (or copy from another Drupal install).
