Migration Assistent: Postboxes not defined

Hey!

The backup and the transferring-process to the new domain worked like a charm, but wenn I want to complete the migration it always gets stuck at a specific file “Backup-13679122918.zip is being extracted…”

When I look up in firebug (console) I see that there is the following error:


postboxes is not defined
(?)($=function())tools....omplete (line 54)
a(t=[Document tools.php?page=wpmove&do=complete, [function()]])load-s...r=3.5.1 (line 2)
a(e=Document tools.php?page=wpmove&do=complete, t=[Document tools.php?page=wpmove&do=complete, [function()]])load-s...r=3.5.1 (line 2)
a(e=undefined)load-s...r=3.5.1 (line 2)

[Break On This Error]

postboxes.add_postbox_toggles( 'wpmove-ma-domain' );
