Woocommerce product pages are blank

Hi,

I have come across this strange behavior… Product pages, when updated, result in a blank page being shown. Changes made to the header or sidebar are not saved, only changes to the actual product description when a draft is saved. I can not save any of the product details.
It doesn’t affect the pages themselves, only the product pages.
Have you come across this before and, if s, do you have any ideas what to do?

Thanks

Found out it was a woocommerce extension Amazon S3 storage. Might be of use to other people here to know that.
