PDO::setAttribute() expects parameter 1 to be integer, string given

This is a regression bug affecting v0.9.0. It has been fixed in newer versions of the application.

To apply a fix, simply follow these instructions:

Open app/System/EnvironmentChecks.php, on line 218, replace:

$pdo->setAttribute("PDO::ATTR_ERRMODE", PDO::ERRMODE_EXCEPTION);

with

$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

Notice that the quotes around PDO::ATTR_ERRMODE have been removed in the new code.
