Hi Zhuan.

I've done a complete new reinstall. I backupped the mysql tables and i reimported them.
Then in upgraded iredadmin to pro and i got presented the question of selfservice. Now I choose yes. As i was curious.
When i logged in with my global admin account, i saw only for that mail account like a regular account.

So i chose the option False in the settings.py (SelfService)
Now i cant login at all.

Is there any option to set it to default? Or can you help me generate a Global admin account through the mysql directly?

Thanks in advance.
