I'm not sure if this is due to the server move, but member-submission of External Link pages doesn't seem to be working.
As a preliminary test, I made a link page to PyChess, and it worked. So, I have not been able to repeat the problem you encountered. If you have any further problem with it, let me know the time and details do that I can check the error log.
