Unpublish Multiple Variants at Once

I have created several characteristics for a product. I have a vinyl decal as the product, in 5 sizes, and approx. 65 different colors.

When I setup the variants, it created 300+ variants, which is what is required. However, they won't be in use all the time.

So I wanted to turn over half of them off, and checked the ones I wanted to unpublish, and clicked the unpublish button.

I get the error "403 - An error has occurred. Access forbidden. Return to Control Panel"

However, if I simply click the unpublish button for each variant individually, it will unpublish that item.

What would cause this? It'd be a pain to have to turn off several hundred variants individually, especially when I have several thousand decals to add!

Any info would be appreciated!

Thanks in advance, Brock

By the way, love the cart so far!

When will this be fixed?
