When trying to connect via BMX connector PHP I get an error stating:
The requested URL/dmxConnections/dmxDatabase.php was not found on this server. But the file does exist. I can connect via Dreamweaver database connector.

Yikes - my first time on this support site looking for help and I find that you had the same problem but your request for help has been ignored for the last 10 months... oh dear! :-(

Hello Edward,
Our extension automatically uploads the connection file to the testing server when you create the connection.
The issue you are having is already explained in the error message - the connection file was not found on your server. This means that you either did not configure your site properly in Dreamweaver, defining your local and remote/testing server settings OR if you did your Dreamweaver couldn't upload the connection file there for some reason.

I am having the same issue

I have entered the information correctly. I can connect to my localhost hosted database through the traditional bindings panel using the exact same info. whenever I try to use the DB connector it gives me a 404 error. Also it is successfully uploading the DMX connections file to both testing and remote servers. but still get the error

Hi Aaron,
As i explained above:
you either did not configure your site properly in Dreamweaver, defining your local and testing server settings OR if you did your Dreamweaver couldn't upload the connection file there for some reason.

I have the same problem and the file is on the server. What might have I done incorrectly in the Dreamweaver configuration?

Thanks....John

I found my error. I had duplicated the site. I had not changed the Web URL setting.
