Static block caching doesn’t work

Magento 1.9.2 has a problem with block caching, so you should either turn off the System -> Cache Management -> Blocks HTML output caching or turn off the caching for just this static block, with the help of the setCacheLifetime(null), like this:

$this->getLayout()->createBlock('cms/block')->setCacheLifetime(null)->setBlockId('block_identifier')->toHtml();
