Can't convert armature to MHX or Rigify

[Jake]

I was just done with my model and was about to add a rig to it until I noticed that both the Rigify and MHX conversion buttons were greyed out. I made a new scene and imported the same figure I got from Daz originally and I could convert it just fine. I also tried to append the old figure to this new scene and it was still greyed out. I also compared both armatures and I couldn’t see anything wrong with the old model. I cannot figure out why it is like that.

The obvious fix would be to simply move the model to the new rig, but I would have to reimport all the morphs again, especially driven shape keys and pretty much start over and that sounds really demoralizing.

Hey, I managed to fix this.

For some reason, the information from the Utilities tab had been completely cleared. I simply copy-pasted and adjusted the information from another older and similar scene and the problem was solved.
