I am trying to post a new sudoku puzzle, but when I click the "create" button at the bottom of the main creation page, it goes to a white screen and does not show me anything else. Is this a site issue, or is my computer having a problem?
It is almost certainly not just your computer. There is some maintenance going on and some bugs appeared; they will hopefully be fixed soon (but probably not tonight anymore).
Ah, very good, then I will just wait a day or two.
I made a mistake during the technical changes last night, but it should be fixed now.
Thanks for letting us know! Please check again, and do not hesitate to report any other bugs you might encounter.
