Moodle: Notice: Only variable references should be returned by reference

Notice: Only variable references should be returned by reference

The issue is with Moodle using an old adodb set that uses "references" which resulted in memory curruption which was addressed in PHP 4.4.0.

To correct perform the following:

Open up the adodb.inc.php file.

The error is around line 2660 of the 4.64 version of the adodb system. Look for the following section:

Change this line:

function &GetAssoc($force_array = false $first2cols = false)

To this:

function GetAssoc($force_array = false $first2cols = false )


Once complete upload this update over the existing adodb.inc.php in your account.



You can also download the latest available version of adodb here.
