I thought this must be just one line or one function. I stared at the code and the database, and didn't get what's the point of the matter.
Sorry. I just could reproduce it, but didn't know why it works that way.
This is my nodebb : http://128.199.248.217:4567/register
Now , I have another problem, there are so many problem....
http://128.199.248.217:4567/
It says that: {"error":"Cannot read property '_csrf' of undefined"}
@Lingyong-Zhang what's the rest of that error, make sure your redis is greater than 2.6.0.
