front-end product view won't show

[spot_d]

Í'm trying to get a magento 1.9 install working after someone else broke it.

All looks to be working except for the product view in the front-end.

Here's the error:

I'm using the rwd/default theme 

Can anyone give me a hint on how to fix it?

Hi @spot_d,

According with your error maybe you can check the file:

/home/webzite/domains/webzite.nl/public_html/app/design/frontend/rwd/default/template/catalog/product/view/type/availability/default.phtml

On line 27 there's a call to method displayProductStockStatus(). That method is not available on class Mage_Catalog_Block_Product_View_Type_Simple. Maybe that is a customiztion on your store.

[spot_d]

Thank you for replying.

This file should have been untouched. Here is the code which seem to be standard in 1.9.3. 

<?php $_product = $this->getProduct(); ?>
<?php if ($this->displayProductStockStatus()): ?>
    <?php if ($_product->isAvailable()): ?>
        <p class="availability in-stock">
            <span class="label"><?php echo $this->helper('catalog')->__('Availability:') ?></span>
            <span class="value"><?php echo $this->helper('catalog')->__('In stock') ?></span>
        </p>
    <?php else: ?>
        <p class="availability out-of-stock">
            <span class="label"><?php echo $this->helper('catalog')->__('Availability:') ?></span>
            <span class="value"><?php echo $this->helper('catalog')->__('Out of stock') ?></span>
        </p>
    <?php endif; ?>
<?php endif; ?>

I see the function in \app\code\core\Mage\Catalog\Block\Product\Abstract.php 

\app\code\core\Mage\Catalog\Block\Product\View\Type\Simple.php extends that one so it should work. I'm lost. Any other ideas?

[Damian Culotta]

You're right. I've missed on the parent class.

Did you tried changing the theme to RWD?

Is it possible that your custom theme has some layout change that points to another block?

[spot_d]

I'm not running a custom theme, switching to a default was my first step. I have disabled a bunch of plugins that would interact with that class, but no luck so far.

[Damian Culotta]

It looks a little bit strange this line:

#2 /home/webzite/domains/webzite.nl/public_html/app/code/core/Mage/Core/Block/Template.php(241): include('/home/teknosuck...')

Has your code some path that contains the string "teknosuck" harcoded?

[spot_d]

that was actually a find and replace gone wrong in that error file tried to hide the site it came from but I guess i failed misserably. Not related to the error. 

[Damian Culotta]

I'm sorry. I'm out of ideas.

I need to check the code to think in another approach.
