I've looked at a few threads on this error, but none of the has resolved my error:

I've create a Item Edit Form menu item, created a user group with basically all posting permissions, and created a user (set as Author) in that user group, but every single time I get:

403 - You are not authorized to view this resource

I've also tried the default Joomla 1.7 template to make sure it is not my template.. same error in both.

Not sure where to go from here..
