Sorry for accidentally banning players of world wide!
Internally, worldwide is handled as region -1. Because of a mistake at the new interface (enabled param printed with identity %u as 18446744073709551615, but scanned as -1), ww was disabled accidentally. I saw it in the night, but I haven't any chance to fix before the morning.
It was an hidden bug in the new websites. I selected Nintendo regions and some others. Then I edited a custom region. While scanning the enabled value for worldwide, the bug becomes relevant and worldwide was disabled.
Then I got a longer PM as reaction of above message at another forum. I'm angry about the educational flair of the PM. Extract:
1.) Don't forget, that this is a private project. I'm not payed. So there is no 24 hours and 7 days per week service!!
2.) Yes, I have a test server and I usually test all new code at the test server before transferring it to the product server. And this code was also tested at the test server first. But I can't test all combinations of input for all situations. Overall, Wiimmfi is very stable, and more stable than some services of multi million dollar companies!
3.) About HTML checkboxes:
If not checked, the param is simply absent. So the input scanner has no chance to find out, why the enabled button is not set (not checked or wrong name).
