invalid birthday when I change anything in the Profile ?

[b4ne]

Hi I asked at vb.com already and they couldn't help.
I realy need some help., everytime I try to change anything (even If I don't and just open Profile and save it without changing anything ) I get the message:

You have enterend an invalid birthday.

I have birthday ticked off in the admin menu so it can't be that.

Has anybody any idea what I can do to fix this ?

Please don't close I try to fix this since 3 weeks now this here is my last hope

Thanks a million for helping

believe it or not I fixed it, for everybody who comes along the same problem, upload the profile.php from and this is importend the latest vbulletin you upgraded or installed.

usually, bugs like these occurs when there is a problem with a file... is someone played with the codes lately ?! adding a hack may bring some troubles sometimes.
