Typoscript from extensions is gone

[typo27]

Privet

I look at template analyzer and I see no TS are included from extensions.
Then a lot of problems occur, for example in the page with ve_guestbook error is shown

Warning: Division by zero in /usr/local/apache2/htdocs/typo3_customers/netnatur/typo3conf/ext/ve_guestbook/pi1/class.tx_veguestbook_pi1.php on line 378

The reason for this problem is missing some TS config, which is defined in the file ext_typoscript_setup.txt of the ve_guestbook extension, but for some strange reason, that TS config is not inlcuded in page template.

What can be a problem here?
