The white flange actually came off with the toilet. There were the typical 2 bolts holding the toilet to the floor, but I didn't see anything else - looks like the bolts were bolting the toilet to the white flange. This is a lower level of a split level home, so on concrete slab.
What do I do here? It doesn't seem like using a new wax ring and attaching it to the white flange would be sufficient - do I need to find some other bolts?
