Pete, Try putting <cfflush /> as the VERY FIRST part of the application. What I find with the 500 NULL errors is that an error is occuring so early that no content even gets flushed the browser. But putting CFFlush in, it sometimes forces the ColdFusion Exception objecto be dumped to the screen.

The code works great under CF8 (and in fact is modified from a site I wrote previously that works perfectly still). It is not using any CF8 features as my host does not yet support it. Tried local MX7 (500 Null) and CF8 (works great - as intended). Any ideas where I should look to solve this problem? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Get involved in the latest ColdFusion discussions, product development sharing, and articles on the Adobe Labs wiki. http://labs/adobe.com/wiki/index.php/ColdFusion_8 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293455 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
