Hello,
I have the following error on admin backend with Smart Search index
Indexer Running
undefined
null

When I try shell
cd /var/www/html/joomla34/cli/ ; php finder_indexer.php
I have the following errors
Starting Indexer
Setting up Smart Search plugins
Setup 17 items in 1.676 seconds.
PHP Notice: Undefined property: stdClass::$page_title in /var/www/html/joomla34/administrator/components/com_finder/helpers/indexer/adapter.php on line 793

• Processed batch 1 in 18.352 seconds. Total Processing Time: 20.029 seconds.

After that I have some indexes on Smart Search, but again
Indexer Running

Environment - CentOS 6.6, Joomla 3.4.1, PHP 5.5, MySQL 5.5
All Search and Smart Search plugins are enabled.
Usual SEARCH component works well.
Thanks for your attention.
