Well, at least it moved your right column into the correct position.

The reason it isn't working is obvious; I can't believe I didn't think to check this earlier. Your wiki is using the new platform. Some features are not yet available on the new platform. Chances are that Activity Feed is one of them. If you want to confirm this with staff, you can use this to ask them if they have an estimate of when the feature will be ported to the new platform.
