Resolution: Not a bug
Affects Version/s: 1.7
Fix Version/s: None
Environment:Linux, I reproduced this bug with both Opera 9.02 and Firefox 18.104.22.168
I navigated to http://moodle.org/login/index.php, entered my username and password (recently reset via the forgot password system) and was presented with "Unfortunately, cookies are currently not enabled in your browser"
My browser does have cookies enabled, and no amount of fiddling around, restarting the browser, or removing cookies seems to let me log in.
I've simplified reproducing this problem down to these steps ...
1) Delete all cookies
2) Put 'http://moodle.org/login/index.php' in the URL bar and hit enter
3) Enter my username and password
4) Click "Login"
I then get the error message in red.
Attached is a Firefox LiveHTTPHeaders dump showing the two requests that occur during this process (with my password shown as ***********).
