Leak around base after replacing wax ring and toilet!

We are having a persistent leak around the base of our toilet. First we replaced the wax ring. Still leaked. Then we replaced it again with a jumbo wax ring. Still leaked. I noticed the porcelain around one of the bolt at the base was cracked near the bolt so we replaced the whole toilet w/ a brand new set up. STILL LEAKS! I'm going crazy here! We did a pretty good job setting the toilet on the ring and felt a good "squish" on the wax when we placed it. I sat on the toilet and rocked slightly back and forth to make sure it got a good even setting. The flange seems to be level with the floor for the most part but I'll be honest that I didn't give it a super good inspection last time we had the toilet off. The house was built in the 20's and has original drain pipes I believe.

Any ideas for me?

Thanks in advance for any tips.

I would suspect either an improper installation or a flange problem.
Can you post a picture of the flange on your next resetting attempt.

IF the toilet can rock, even when it is at the floor, the wax ring seal will usually be damaged.

When you have the toilet up, clean the old wax ring off of the toilet and the flange. Then set the toilet in place but without the wax ring. It should be solid with absolutely no rocking. If the is movement, you will need to shim the toilet to level it and take out the rocking.

Had you considered the possibility of condensation rather than a leak? Cold water (especially in the winter) and a warm, hot bathroom after a long shower or bath, could mean just drips from condensation.
