No X, Y, Z, or A listed in mdi when setting origin

Something strange has happened. I'm using version 2.7.14 with Touchy. While trying to install a new quadrature spindle encoder, I crashed Linuxcnc several times. I solved the crashing problem by fixing a typo. However, now there are no axes listed in the mdi. X, Y, Z, and A are all missing. I cannot set the origin or even do a G1 from the mdi. All that is listed are Q and R. Even older config files that previously worked do the same thing. I tried reinstalling Linuxcnc, but the same behavior persisted. Am I stuck in a wrong mode? Any ideas for me?

I should have mentioned that I am using a 5i25 and a 7i76. Also, all the axes home and jog just fine.

I'm sorry. I meant to post a follow-up. There was a problem with the estop circuit. Once that was corrected, all the axis letters in the mdi appeared as normal. Thanks so much for checking.

Yes, that is exactly how my screen appeared.
