ALIAS: Empty error message from utility.

[MarkcRobinson]

Panel version 10.3.1 OS Linux 2.6.33.5-rscloud

Symptom:
When I create a Domain Alias, or try and change the mail settings of an Alias this message comes up.
____________________________________________
ERROR: PleskException
Mailmanager::delDomainAlias() failed: mailmng failed: Empty error message from utility.

0: DAliasManager.php:404
DAliasManager::delDAlias(object of type DAlias)
1: domain_aliases_remove.php:32
_______________________________________________

UPDATE:
When I create a Mail Account in any domain, it appears to work. When I try to delete that email account, I get an Error. "Error: Unable to delete some of the selected e-mail addresses. "

When I try to delete an entire domain, I get a message from the CP "Internal Error"


What I've already tried:

1. changed /etc/php.ini safe_mode to off

2. changed value in mysql from
+---------+--------+
| param | val |
+---------+--------+
| version | 010120 |
+---------+--------+
1 row in set (0.00 sec)

to

+---------+--------+
| param | val |
+---------+--------+
| version | 010310 |
+---------+--------+
1 row in set (0.00 sec)

3. ran update mail set spamfilter = 'true' where postbox = 'true'; on psa database

4. and we restarted the services psa mysql and httpd

5. checked that Plesk configuration file has proper permissions
