@andreearadacina21, here ya go
FYI, I downgraded my production site to 32.0.20 and the add to cart now works.
So you can observe this issue, here is my staging site, which is running 32.0.22
https://280.150.myftpupload.com/product/urc-tkp-100-custom-engraved-button-cap/
I also am having this issue, even when upgraded to 32.0.22.
It appear to only be with items that include a text input field.
I have the same problem, I am a e-commerce store if that matters.
I thought the plug in would prevent new users from actually logging in until approved.
