how to reinstall civicrm 4.6.4 in wordpress
I'm not sure if there is a better answer but this is what I resorted to:


Clear Cache
Disable civicrm plugin
Delete /templates_c/ contents
Copy civicrm database to civicrm.sql using mysqldump and delete all tables (or drop / recreate database)
Move /civicrm/civicrm.settings.php tocivicrm.settings.tmp
Enable Civicrm Plugin
Run Civicrm install script http:///wp-admin/options-general.php?page=civicrm-install
Page Civicrm is created and I presume other civicrm install magic in wordpress
Disable civicrm plugin
Replace civicrm.setttings.php with civicrm.settings.tmp
Restore civicrm mysql dump (e.g. mysql civicrmdb &lt; civicrm.sql)
Re-enable civicrm plugin
