Hi there,

So i'm using softaculous to install drupal 7.31 on a shared host running php 5.4.31 & mysql 5.5.37-cll.
If I install 6.31, I don't get this error.

After the 7.31 install, I get the following error on the websites main page:

Warning: PDO::__construct(): The server requested authentication method unknown to the client [mysql_old_password] in /home/ggs/public_html/drupal/includes/database/database.inc on line 307
Skip to main content

The website encountered an unexpected error. Please try again later.
