[Hans]

The bug you fixed in earlier version, is back.
You can not enter agents in the web interface.  
If you use the quick start, it shows agent: [   ] max=0
You can not enter 1 => error, if you enter 0 it complains about minimum 1 agent.

regards,
Hans

Thanks for reporting.

 

However, This is intended. The way I fixed is to allow only "Save" when 0 agents are available.

 

It does not make sense if we allow save and start action when no agent are available.
