Forum Blank page in contact us page with sendmessage.php
 

I am using Vbulletin 4.1.12 with Nginx instead of Apache and using gmail's smtp for mailing purpose. It's all going good. I'm not able to send emails through "Contact us" form of vbulletin.


When I try to submit the form in contact us page, It displays a blank white page after clicking the "Send". The url to blank page is "/sendmessage.php?do=contactus". Everything is working fine on Diagnostics page of Vbulletin Admin.
