[CWB] CQPWeb 3.2.11 DbType could not be converted to string

[Vincent]

Hi,
I downgraded to CQPWeb 3.2.11.
When I'm trying to do a frequency breakdown this error message appears
(and it's not working):

[Tue Apr 25 13:51:00.535777 2017] [:error] [pid 21373] [client
xxxxx:53750] PHP Catchable fatal error:  Object of class DbType could
not be converted to string in /home/cqp/CQPweb/lib/db.inc.php on line
501, referer:

Or this:

Thanks.
