Conditional logic broken

Hello we have been using ppom for over a year without any issues but recently it broke on the front end.

In the page I’ve linked for you, you’ll see “assembly options”, this consists of a yes and a no radio button, together with a quantity field, and a hidden field of price.

What used to happen is the quantity field would only be displayed if Yes was selected. Now it always displays.

I checked the backend and when I saved it said the database has changed since version 22, we should disable and re-enable the plugin, but still it remained broken.

We have thousands of products mapped to these so it will take a huge amount of work to rebuild it.

Can you offer any support or insight?

Thanks,

Gary
