I just did a fresh installation of Magento 220.127.116.11 and I am seeing some very odd behaviour with the customer login form.
In Chrome (version 36) the login form does not work. I am just redirected to the login page. There is no error message shown on the page. However, when I open a new Incognito Window, I am able to log in just fine. Thinking this was a cookie problem, I cleared out all my cookies from the browser and tried again and I got the same results. In both cases, I am able to log in to the admin panel without any issues.
I have also tried this in both Firefox and Safari. Firefox I would see the same thing happen (but not consistently and I could fix it by clearing the cookies) and I could not replicate in Safari.
I have never had an issue with this in any other version of Magento. Is there some kind of fundamental change in the way Magento handles cookies in version 1.9 and/or is there something I can do to make this more stable?
abc.comit was then redirected to
www.abc.com. In this case, the browser was setting the cookies for both and logins specially stopped working, but if i manually delete the cookie that was without
wwwthe logins start working again.Can you check if same is the case with you too?
