I've got a message from a member of polish smf support that he's not able to sign in. I checked it and there's a database error for anyone that tries to login (it's fine if you're logged already)
Fixed.. There's a new column in elkarte_membes, which tracks the last used one time password OTP). It's an additional protection to ensure the one time password is only used once..
ALTER TABLE [icode]elkarte_members[/icode] ADD [icode]otp_used[/icode] INT(6) NOT NULL DEFAULT '0' ;
Was that something related to the recent upgrade or just the further updates of the files?
