We are working to resolve an issue on the product creation page. We will update when we have a fix in place, hopefully in the next few hours.
Update - 11:00AM EST
We have determined that the product image upload component is the reason why the product page is currently failing. We have removed this functionality from the product setup page for now so that new products can be loaded while we work to resolve the issue with the image upload.
Update - 3:00PM EST
We have resolved the issue related to the product image upload. All product creation processes should now be working properly.
