I installed fresh Drupal 7.17 and then imported values from older db.users (Drupal 6.24) table to newer db.users table without any issues.
- users cannot login into the system
- even after requesting new password, once trying to set password and save. It throws error.
PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'signature_format' at row 1
I am using
Apache version 2.2.23
PHP version 5.2.17
MySQL version 5.5.28-log
