Hi, My Client has all of a sudden come across this error when trying to update a product or save a product.
Oops! The form contains 2 errors which have been highlighted below.
Please fix the 2 errors and then try submitting the form again.

The is no errors that are present?

The variations may have something to do with it. here is my test producthttp://singlesinthecity.com.au/store-2/products/sundowners-the-avairy/

Also the Wolf Lane one is affected too. I need to add a featured image, but get the error after clicking on update.

We had other issues with this site in recent weeks, Yoast SEO plugin was a cause of conflict. Your support suggested cutompress was too.

After you last time looked at it, the site was toatlly messed up, By deactivating the theme and then activating again, all my layouts disappeared, so please do not do that again.
I will activate support access now.

Any clues to what the problem might be.

There was a reference to this error in an post from last year.
