Removed MMU2-Octoprint stopped working

I physically removed the MMU2S from my MKS3.  I powered it back up, and it gave me an "autoload filament" option, which I did, and the filament extruded.

So I logged into OctoPrint, which I have been using since I got the printer, it connected, but now it won't let me select a file I've uploaded, and it won't give me a temperature graph.  I have checked that all the USB cables are plugged in properly, and power-cycled the RasPi, but no luck.  Removing the MMU2s involved removing four wires (I didn't remove them, a friend was helping since I have some serious mobility problems).  Everything seems to be fine, but no printing is happening.  It might be an OctoPrint problem.  I am going to post there

Did you change your printer profile in Octopi, not sure of all the differences but theres number of extruders which would need setting to 1 rather than 5.

Octoprint changes:

Settings

Printer profile
Edit printer profile (Action)
Hotend & Extruder
Set the Extruder value to 1

Remove the data and the power cable from the MMU2:

(remove the violet marked plugs)

@flounder

you don't have to change anything on the octopi system, but as I just listed in the gui octoprint:

Apologies for causing confusion I should have said Octoprint.
