I'm encountering the same exact problem, console printout is word for word the same. After I opped myself every single command attempt through the client results in that. Using the Direwolf20 1.6.4 server downloaded straight from the ftb launcher with absolutely nothing added or removed. I didn't find anything about this with a quick search in the modpack bugs report thread, should I do some additional tests and then cross post this there?

I had this issue and was able to resolve it. I think my fix was to disable in-game whitelisting.

My setup that now works:
* Use McMA's whitelisting as normal (add people to users and groups, enable whitelisting under configuration -> features)
* Manually add admins into the stock ops.txt file
* server.properties: white-list=false

Please post back if this works for you.
