I updated a custom module to use WebAPI2, Newtonsoft JSON and EF6 and I needed to include these .dlls in the bin folder of my website (DNN 7.2.1)

However, since the update, I noticed that I can no longer post on the Journal Wall or Messages - it looks as though the core services framework are failing with the new .dlls.

So my question is: Does this sound like a configuration issue and it is a valid situation? (ie. should I update those .dlls and expect the rest of DNN to work as before?)

Here are the Javascript error messages when you try to post on a Journal Wall on PokerDIY.com
