Encountered a PHP Fatal error due to an uncaught mysqli_sql_exception in the system. The error message indicates an issue with SQL syntax, specifically when handling a name with an apostrophe.

The follow log is what my team and I found when one of us found that changing the account password caused the page to go completely white and the POST go return a 500 error code. In the instance the last name would be something like O'Connell and the Connell would be in place of LastName in the log.
