I'm using the latest version: Version 2.00+ Build 121121
And when I try to access the survey (via the link in the invitation email, or after inputing the token), I get the following error (also attached a save of the error I got):
CDbCommand failed to execute the SQL statement: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute
The server is: Apache/2.2.3 (Red Hat) DAV/2 PHP/5.1.6 Yii Framework/1.1.10
How can I solve this?
Thank you in advance.
