Attention: All members with diacritics in their names, after the recent upgrades, some users who have diacritics in their name have had problems logging-in.
We thought we fixed it, but apparently the error codes are still coming up. We are working on it some more.
In the meantime, if you want to post, we can temporarily change it to the same name or other name, without diacritics and then you should be able to log-in with the same account, posts, etc. Just send us a pm or email.
