Can't revise multivariation listings

[mretro1]

We are having issues adding stock to multivariation listings. When we click on revise item nothing happens for a couple of minutes then we get an error message saying..there is a problem..please try again. Any ideas

I use multi-variation listings too. I love using them, but I have always found them fussy. They are just fine if you leave them as they are, but start getting mixed up when I try to revise them.

I am also experiencing the exact same issue with multivariation listings. Hopefully this will be fixed soon.
