Magento: Template path not showing

Problem:-

For some reason the template path hints are not displayed.

I went to the admin panel and turned them off and on again, then cleared the cache. But they are still not displaying.

Solution:-

Try to check if your configuration backend for System > Configuration > Advanced > Developer Client Restrictions is empty or set to your correct IP address (the last case is the best pratice).

Or to follow the idea of @fabian-blechschmidt, check if you didn’t have overwritten one of the methods in your Block:

• Mage_Core_Block_Template::fetchView()
• Mage_Core_Block_Template::renderView()
• Mage_Core_Block_Template::_toHtml()
