Can no longer create MySQL functions

[Frank Mena]

I have been using AppFog for a while with no problems loading a mysql script that includes stored procedures and functions.

When I tried to update my database, I am now getting the following error:

Error : You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)

Here is an example of a function that I could create previously:

delimiter ;;
CREATE  FUNCTION `nextSyncValue`() RETURNS int(11)
    READS SQL DATA
BEGIN
 DECLARE next INTEGER;


 UPDATE syncvalue
 SET LastValue = LastValue + 1
 WHERE SyncValue_ID = 1;


 SELECT LastValue
 INTO next
 FROM syncvalue
 WHERE SyncValue_ID = 1;


 RETURN next;
END
 ;;

Why can I no longer create MySQL functions but still create stored procedures?
