I installed DBQ (Database Query) 1.2 successfully with Mambo 4.5.2, PHP version 4.4.1 , MySQL version 4.0.25-standard . I followed the DBQ documentation for "Quick Start".
I was able to parse the sample query. When I tried to Preview the query in administration I got the error.
PHP Warning: Invalid argument supplied for foreach() in /home/mydomain/public_html/components/com_dbquery/templates/default/ExecuteQuery.Results.html.php on line 64
Not sure what the problem was I unistalled DBQ 1.2 and tried to install DBQ 1.3 from Joomla. I was not able to install DBA 1.3 so I reinstalled DBQ 1.2.
After this unistall/ install exercise I now have a new problem with DBQ 1.2.
When I try to create a new Category by clicking the "New" button a Javascript "Access is Denied" results (line 517) with the URL
http://mydomain.com/administrator/index2.php .
Not sure what happened. I really like the idea of using DBQ, it seems to do everything I need.
