Add domain alias not working

[kluckit]

When I click: Add new domain alias (Neuen Domain Alias hinzufügen) an empty page appears.
(...:8443/plesk/client@73/domain@173/domain-alias@new/properties)

I am not able to add new aliases since one of the last microUpdates.

We are using Plesk 10.4.4 Update #41 on Microsoft Windows 6.1;build-7600;sp0.0;suite1296;product3

On a second machine (10.4.4 Update #39 Microsoft Windows 6.1;build-7601;sp1.0;suite1296;product3) the same. My both Linux machines are working fine (so far).

that helped: http://kb.parallels.com/en/113637

not the resolution, (Plesk 10.4 MU#36 or later is installed)

but the workaround:
mysql> ALTER TABLE sessions CHANGE data data MEDIUMBLOB;
