Dear Faraz,
Is it working fine before ? Please let me know about your Views and WordPress version.
If possible please try the following.
1) Take a backup then inactivate other plug-ins and check it is working or not
2) If issue exists, also confirm it is working or not after switching to default 2012 theme
3) Please check your debug log file and look is there any warnings or error related to this. Please check this tutorial for more details http://codex.wordpress.org/Debugging_in_WordPress#Example_wp-config.php_for_debugging
