I encountered this issue when adding a new post in blog widget. The screen becomes grey when I clicked on the "Add New Post" button. This causes me not to be able to submit the post.
What could have gone wrong?
This looks like a case to submit to Tech Support, but you can bring up the Developer window (F12) and see what the page is actually trying to do.
