Cannot apply generated templates to a site in Parallels Presence Builder 11.5.6. The following error is shown in GUI:

The following records appear in the log:

2013-09-14T00:58:25-04:00 [EMERG] /sitebuilder/JsonApi/ SB_Widget_Exception: Widget type 'hidden' is not supported.
file: /usr/local/sb/include/SB/WidgetBroker.php
line: 23


The problem is caused by hidden widget 'search' configured in Parallels Presence Builder 11.5.6:

~# cat /usr/local/sb/config | grep hidden_widgets
hidden_widgets = search


  1. delete 'search' from 'hidden_widgets';
  2. add 'search' into section 'restricted_widgets' instead. This option is missing by default, but you may safely create it in the configuration file.

Developers plan to fix the issue is actual code of Parallels Presence Builder since version 11.5.7. Bugs are 142937, 142938.
