Hello
I have exactly the same problem but with Replete.
Opened a new thread but nobody replied.
This is the original post:

Hi
My website crashed and everything stopped working after updating to the latest wordpress. I made sure all the plugins were up to date and cleared the cache and the website went back to normal, at least on my end. Since then I have received two emails from customers stating that they can’t see the prices for variable items, it’s also usually quiet and I have hardly sold anything since updating the website.
I have checked my website on different devices and both Win and Mac but can’t find anything wrong with it.
Below is a screenshot that a customer emailed me this morning:

Thank you for your help
