I started a new Vanilla installation in order to perform a functionality test and am having a signin problem. Most people can sign in, but it seems that some people can't. They click the sign-in link, enter their un/password and are taken back to the main page. They do not get a notification, and are still in a "Signed out" state. Is this a known issue? Possibly some cookie / browser security base settings must be in place? Thank you!
I'm getting the same or similar problem on my first test installation (on my localhost). I sign in with the admin name and password, hit Proceed, and get the Not Signed In page, with none of the admin options.
I'm not expert with cookies. Could it be because my local server wont handle / create them properly? I should add, remote Vanilla systems (like this one) work fine.
