Hello
I have upgraded my forum from previous version.Every thing is fine but the event log is filled with the following error:

Invalid column name 'Birthday'.
Invalid column name 'Birthday'.
Invalid column name 'Birthday'.
Invalid column name 'Birthday'.
Invalid column name 'Birthday'.

I have attached my event log.What is the problem?

Thank you

It happens, because profile doesn't contain a new field 'Birthday'. Simply save any user profile once and it will be added.

Shouldn't it be created during setup process?

Agreed.It is already in Bug Tracker here  and hopefully will be fixed for next release.

It should, but a straitforward upgrade is rather tricky in the case. The error is really a notification, because Birthdays feature is unavalable anyway, until a user saves his/her profile.
There're reasons for it, especially for forums with very large number of users.
In total: this is not a bug and will not be fixed by me, but if someone from YAF developers would option to make it he could do it.
