Problem:
The following error appears when trying to access moodle:

Notice: Only variable references should be returned by reference in /home/username/public_html/moodle/lib/adodb/adodb.inc.php on line 2689

Resolution:

Change in the file adodb.inc.php arounf the line 2680:


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

to this


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