I wanted to add that I have the same problem. Even worse: I can’t even update the product page with thousands of variations…
I have the exact same problem. Pages do not have any guid… I don’t know why though and I don’t know how to fix it.
I disabled commenting on pages for now (luckily all pages get disabled for intensedebate if I choose to disable one of them via the commenting module below the page).
PLEASE do tell us when this problem is solved! =(
