"Place Bid" button no longer working

Installed the free version, set up a 100+ item auction, tested thoroughly, and launched.

And *kerthunk*. The place bid button has stopped working. I’ve tested in several different browsers, but the same thing happens — nothing.

You are welcome to look at my site: https://tookaleapfarm.com/silent-auction-to-benefit-ark-animal-sanctuary-2/

It looks like several other people have reported this issues recently, as well.

(Note: I purchased the Pro version, but get an error installing that and am reluctant to play too much for fear of deleting my auction items. Which would be tragic.)

Thanks for any advice you can provide!
