Can not solve this. I have created other connections to the same server without issue. I can build the connection and it tests properly. I can see and load the table -- but when I test the connection to show the content I get the Error Querying Database. I've tired rebuilding the connection to no avail. Very frustrating.

Hi Joe,
Is this only happening on the test data source window? What if you add the repeat region with your data on the page? Can you please provide a link to this page?

I get a blank page when I test live.

There is an "500 Internal Server Error" on your server, when i load the page. Please check your server error logs for detailed error report.

Can you please make sure the: /ScriptLibrary/dmxDatabaseConnector/sqlBuilder.php is created and uploaded to your server?
Also what is the remote folder you are uploading your files to? It seems there is some mismatch between the local site/folder structure and the remote one... which may be causing this issue.

That fixed it -- and yes, the site structure is a bit of a mess, it's one of the reasons the client is having me redo the site with newer tech and cleanup what is there.

Thanks for the help!

i have the same problem i get a blank page and no errors on log file.
