[Dimka]

Hello i am trying to migrate from plesk 7.1.4 to 7.5.0 and i have a Problem (MailSystem Dump Error):

Plesk panel error report:
===========cut===============
Migration Agent Upload:
Unable to create a description for the migrated objects:
Eror during dump retrieval
Lost connection with the remote host
===========cut===============

PleskX.pl script manual debug:
===========cut===============
./PleskX.pl --dump-all
....
......
..........
Dumping domain mailsystem
DBD::mysql::st execute failed: Query was empty at ./PleskX.pl line 1286.
Error: exesute sql:
Query was empty
Can't call method "rows" without a package or object reference at ./PleskX.pl
line 1184.

Note: manual mysql query works normally, I'm using Mysql server v. 4.0.22:

===========cut===============
mysql>SELECT m.id, a.password, a.type FROM mail m LEFT JOIN accounts a ON
m.account_id=a.id WHERE m.dom_id=11 ORDER BY m.mail_name;
+----+----------+-------+
| id | password | type |
+----+----------+-------+
| 84 | blahblah | plain |
+----+----------+-------+
1 rows in set (0.001 sec)

Any advices are welcome

Thanks In advance
