I've made a module that, in my localhost works fine.. The block shows up and ok, but in "livehost" the block don't appear, so I created a controller to make some tests and see what is the problem.

public function minhaactionAction(){

    $this->loadLayout();

    $block = $this->getLayout()->createBlock('slideproducts/slideproducts');

    var_dump($block);

    $block->setTemplate('slideproducts/slideproducts.phtml');

    $this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();

}

In my localhost the block continue, but in site var_dump($block); returns bool(false). I search for a light by days and nothing yet, I hope so someone can help me to solve this problem.

If I use the $block->setTemplate('...'); it gives an error:

"Fatal error: Call to a member function setTemplate() on boolean in /home/httpd/htdocs/..."

Obviously, its because the createBlock function returns false.

(Tipo de bloco inválido:) is, Invalid block type

I suspect that versions of your Magento in localhost and live versions are different.

After Magento version 1.9.1, Magento introduced a new feature of block permissions.

Now if you are introducing a new block class in Magento system, you need to allow it from:

System -> Permissions -> Blocks

Click add new block where block name slideproducts/slideproducts and isAllowed -> Yes

Now save. Clear cache. Hope this will solve your problem.

Your action code should be

public function minhaactionAction()

{

    $this->loadLayout();

    $block = $this->getLayout()->createBlock('slideproducts/slideproducts');

    var_dump($block);

    $block->setTemplate('slideproducts/slideproducts.phtml');

    $this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();

}
