25 year old toilet, all of a sudden, seems to be shifting and the tank is now angled and one side is touching the wall, nothing seems loose, or wobbly, but it must be moving, since it never was this way before- any ideas about what needs to be done to correct the problem?
The tank to bowl bolts need to be replaced. The tank will need to be removed and new SOLID BRASS BOLTS and the gasket will need to be replaced. When you tighten the new bolts on the tank, lay a two foot level across the tank with cover removed. Tighten each side a little at a time. I always tighten the tank down until it just touches the raised rib on the bowl, and no more than that. You can buy generic tank to bowl kits, but make sure the bolts are solid brass.

Check toilet flange/wax ring/mounting bolts
