在修改生日时，不可以设置未来的日子，DOB就是 Date of Birth，得设成1988年5月12日而不是2018年5月12日。
（不小心暴露年龄了）
在网上查询相关解释时，没有中文注释，特此备注。
以下为原文：
[#8093] - Invalid DOB on user registration results in 500 error upon redirect, instead of successful redirect and display of validation error
Steps to reproduce the issue
- Require Date of Birth (DOB) on User Profile
- Attempt to Register a user using an invalid date for the DOB - ex: 1970-13-13
Expected result
- Registration will fail, redirecting back to the registration form and showing the DOB validation error"Registration failed: The date of birth you entered is invalid. Please enter valid date."(PLG_USER_PROFILE_ERROR_INVALID_DOB)
Actual result
- Instead, the redirect fails on the invalid date, resulting in a 500 error page showing"DateTime::__construct(): Failed to parse time string (1970-13-13) at position 6 (3): Unexpected character"
System information (as much as possible)
- PHP 5.5.0RC3
- MySQL 5.5.32
Additional comments
- Should be trivial for someone else to try to reproduce and confirm or deny
