Hi there. 

We're having trouble getting debug logs working for our developers.

we are not able to get the debug logs for rest call API. on the following sandboxes
1. test (cs21)
2. v2dev (cs4 instance)

We have a site named 'RestCalls' and all rest resources belong to this site. we also tried adding the guest user for restCalls, however, we won't be able to get the debug logs for the call we made for these rest API. 

one more interesting thing, in CS21 even debug logs for anonymous execution is not populated

any help would be greatly appreciated! 

Thanks so much!
