Hello all,

When I tried to check challenge for the Enable Salesforce Knowledge module, appers "Challenge Not yet complete... here's what's wrong: 
Knowledge doesn't appear to be enabled.". But I checked and I did all that requeried. What could be happend? (I attached print screen for the user configuration when you can see that the Knowledge User license is assigned, and a print screen showing that knowledge is enable and the default knowledge language is English)

Can anyone help me?
Regards
