Error pdotools-1.9.1-pl3

Hi

I'm getting repeated errors in the MODX Manager log — Revo 2.3.2

[2014-11-20 17:28:01] (ERROR @ /var/www/vhosts/domain.com/httpdocs/core/components/pdotools/model/pdotools/pdofetch.class.php: 87) PHP warning: PDOStatement::execute() [pdostatement.execute]: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens
[2014-11-20 17:28:01] (ERROR @ /index.php) [pdoTools] Error HY093:

How do I fix this?

Thanks
