This mostly happens when you call a helper that's not defined - Magento then assumes the default Mage namespace.

You can search the code of your extension for any references to the sintax helper. This can be direct references like Mage::helper('sintax') or $this->helper('sintax') or less obvious ones in your xml files (config.xml, system.xml or any layout update files) using the module attribute, like:

        <catalog translate="label" module="catalog">

Finally i found the solution. The reason to get this error is this extension is broken extension.
