I should have mentioned that after drying up the standing water behind the toilet, I kept check on the toilet valve and lines and they were not leaking after a day's use. I made sure the AC unit was draining ok. We have had a lot of rain and it is most likely a leak from the roof. The wall is damp to the touch in the corner behind the toilet a little higher than a foot, maybe a couple of feet. then radiating out a foot or so and a foot or so high.
Finding the source of the leak is the challenge and a real mystery. If it does not rain in the next few days and the walls continue to dry, then it is most likely a roof or slide seal leak.
