Unable login to my self-hosted Askbot [closed]

edit

Could anyone tell me how to fix this issue?

I cloned the branch 0.10.x and set up it using Python 2, then successful migration, creating super user and collcting statics.

When I started app and tried to login. At the first time it's OK, but from the next time nothing happened, I mean I can't login any more.

I tried 0.11.x branch and master branch, but the result were same.

When sending password reset email and clicking the link in it, only at that time I can login.

No log and message.

Any idea?
