I've been playing Prison Architect for a while now, I have all the rooms, and everything set. However, my prisoners don't go outside of their cell, even at feeding time. I don't know if they're supposed to do stuff like leave their cell, but they're also starving for some reason and I don't know what to do.
Here's a picture of the prison:
go to your deployment, is your prison blinking yellow?
The prisoners should be able to leave their cells to go to certain rooms such as the yard and to get food etc...
Usually it won't class your prisoners as uncuffed in case they believe there is something wrong with the prison.
My thoughts also come down to the cells needing to be connected to a hallway which attaches to each other room/building as they need to have certain paths allocated to staff/prisoners/High Warning Prisoners.
Look at what areas are marked as. i had this problem because one of my main hallways was marked Medium only so my high risk guys would do nothing else. had to switch back to shared. worked fine after that.
Example here: 
There you can see paths connected to each cell and the locations they can go to.
I see your kitchen equipment is smashed together in the same room as the Canteen, but I don't see a separate zone in there actually designating any space as a Kitchen.
If you have no Kitchens zoned, it doesn't matter if mealtime is scheduled, no one will go work in one. Cookers don't do anything unless they are in a kitchen and get worked, so as far as I can see, nothing gets cooked, nothing gets served, and nobody eats.
