WebSphere Commerce 7 | User Login Failing | After Logout, it doesn't work

I have noticed in my local toolkit, User Registration was working fine. But, if you logout from the store, I am not able to login again with the same user. And in the logs also, I didn't notice any exception

Issue:
WC\xml\member\MemberRegistrationAttributes.xml was some how corrupted and it was empty

Fix:
After replaced WC\xml\member\MemberRegistrationAttributes.xml with the original file and after build and deploy, it started working fine

Thanks Vivek Kumar for quickly noticed the issue.
