I have entered into the online form all of the information I have available, to add a new title. My contribution link is 180611-225823-942200
The last thing I did was to check the box at the top for "Explanation for missing information".
Now everything I try, including trying to "Save for later" and trying to enter text in the "Explanation for missing information" box, produces an error with pink-color background:
An error occurred on submission, please try again.
I cannot go forward, and I cannot go back. I am stuck.
