Configuration admin - check.csrf could not be found

[Kevin]

If somebody encounters the log message:

Code:

Configuration could not be found. Package 'admin', Name 'check.csrf'

Then please switch to Administratiopn / Configuration. Scroll down and create a new configuration with the exact same package and name:
Package: admin
Name: check.csrf
Type: boolean
Value: 1

Somehow I must have missed to create that setting during an upgrade, sorry!
