catalano Posted September 29, 2015 Share Posted September 29, 2015 Hello all, I've submitted this to tech support, but I figured I would ask here to see if I can get this solved faster. I upgraded our installation from 5.3 to 6.1. I did a full install as per the instructions. When navigating to the site to complete the installation I get this error: Warning: PDO::__construct(): The server requested authentication method unknown to the client [mysql_old_password] in /home/c2it/public_html/billing/vendor/illuminate/database/Illuminate/Database/Connectors/Connector.php on line 47 Critical Error SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client Any ideas what this is? Thanks, Chris 0 Quote Link to comment Share on other sites More sharing options...
rkatz0 Posted September 29, 2015 Share Posted September 29, 2015 Sounds like you didn't load the PDO extension into PHP. 0 Quote Link to comment Share on other sites More sharing options...
catalano Posted September 29, 2015 Author Share Posted September 29, 2015 Whatever is running is the same that was running on version 5.x. I just checked in my cPanel and the site is set for php5.4 as native. Sounds like you didn't load the PDO extension into PHP. 0 Quote Link to comment Share on other sites More sharing options...
rkatz0 Posted September 29, 2015 Share Posted September 29, 2015 Not addressing the question does not make it go away! PDO is loaded/running or not? On one working install (if you cannot get into WHMCS to check you can get it through phpinfo(): API Extensions mysql,mysqli,pdo_mysql PDO PDO support enabled PDO drivers mysql, sqlite pdo_mysql PDO Driver for MySQL enabled Client API version mysqlnd 5.0.11-dev - 20120503 - $Id: 3c688b6bbc30d36af3ac34fdd4b7b5b787fe5555 $ Directive Local Value Master Value pdo_mysql.default_socket /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock pdo_sqlite PDO Driver for SQLite 3.x enabled SQLite Library 3.6.20 0 Quote Link to comment Share on other sites More sharing options...
catalano Posted September 30, 2015 Author Share Posted September 30, 2015 Yes, the base load of php 5.4 includes pdo and the appropriate sql drivers. I heard from tech support. The problem was that the pw for the dbase user was using the older hash string. So they had me change the dbase user pw in cpanel and that fixed it. 0 Quote Link to comment Share on other sites More sharing options...
