OperationalError: attempt to write a readonly database

[bf-ckiendl]

I installed Bots straight as described in the documentation under Windows: Got the Python 2.7 Installer from the official site, got bots-3.2.0.win-amd64.exe from Sourceforge, installed both, all well.

Tried to run bots-webserver from Start Menu and...

Log in

OperationalError: attempt to write a readonly database

I'd take a wild guess and assume Django's SQLite-database was written in some system folder or is owned by the administrator I installed it with or something, but since Django was set up automagically in the background, I don't know where that DB is or in what state it is.

I was unable to find any similar issues. Is this a known problem? What could cause this? Is the documentation missing a step?

Which version of Python do you have installed? I had this exact error running Python 2.7.14. I reinstalled Python 2.7.10 and now I don't get this error.

2.7.16.

I got it to work, though: https://github.com/bots-edi/bots/issues/68#issuecomment-545379337
