I'm sorry, I don't have a solution for this problem for you, but kind of a work-around. Instead of updating your URLs, you can move them to trash and they will be updated automatically one by one when your website is displayed.

I can also offer you our paid support service to try solving the problem directly on your server. If you're interested, please contact us at Diese E-Mail-Adresse ist gegen Spambots geschützt! Du musst JavaScript aktivieren, damit Du sie sehen kannst. .
