I am migrating a Drupal site to local environment. Currently I get the following error when I refresh the browser:
Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY'
I have read that it may be a problem with pdo_mysql extension. However, mine seems to be installed and enabled. What else could it be?
Here is the relevant excerpt from the php.ini file:
