RuntimeError at /, maximum recursion depth exceeded while calling a Python object

After upgrading to 1.9.0, I can no longer access the panel because I receive the following error:

RuntimeError at /
maximum recursion depth exceeded while calling a Python object

See full error in ticket #IK8P4A.

Open /usr/local/CyberCP/CyberCP/setting.py

And remove redundant

'django.middleware.common.CommonMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware',

Keep only one of each. Then systemctl restart lscpd

Thanks! Fixed! For others who may be following these instructions, note the following typo:

*settings.py
