I have a virtual server on Microsoft Azure. It has IIS 8, PHP 5.4 and a Joomla 3.3 site installed on it. This is a brand new install where I am migrating a site from a different location using Akeeba Backup(v4.0.2).
I am seeing a problem when I try to log into the Joomla site at either the front end or the administrator side. In both cases I enter a valid username/password combination (verified) and the screen just jumps back to the same page. I get no error or notification of an invalid login, but it does not log in.
I verified the users I am trying and everything looks good at that level. I have error reporting set to its highest level in PHP and Joomla. So far I have seen no errors anyplace. The web pages do seem to be posting the login credentials to the server and the page is refreshing. There are no JavaScript errors that I have found.
The one strange thing is that Joomla does not seem to be writing anything to the Logs folder. On each login attempt it should be appending a log file, but nothing at all is happening in that folder.
In some posts people have noted that this could be a permissions issue and cause a silent failure. Based on that I verified that the IIS_USERS account had full permissions to that folder.
I am beating my head against the wall on this. Does anyone have an idea of what is going on or thoughts on how to debug the problem?
