The error on the screen shot is saying you only have locked ruleset on your AccessGroup. The other one is different. Do you have an associated task on your log files?

Hi Marc,
Thank you!

I'm a beginner at Pega.

Could you please explain where I unlock my set of rules?

I have no tasks associated with my log file, it was my first access!

Can you help me?
Thanks!
