Magento – Magento 1.9.3 additional information under details

I found the problem. There is an extension on the our Magento Instalation called amasty color swatches which has a script on the page which disables the additional info tab.

here it is:

<script type="text/javascript">
                        var amConfAutoSelectAttribute = 1;
                        confData = new AmConfigurableData({"9":{"short_description":"<p>Lorem Ipsim<\/p>","description":"<p>More Lorem Ipsum<\/p>","not_is_in_stock":false,"attributes":"    <h2>Additional Information<\/h2>\n    <table class=\"data-table\" id=\"product-attribute-specs-table\">\n        <col width=\"25%\" \/>\n        <col \/>\n        <tbody>\n                    <tr>\n                <th class=\"label\">TEST ATTR<\/th>\n                <td class=\"data\"><p>More Lorem Ipsum.<\/p><\/td>\n            <\/tr>\n                <\/tbody>\n    <\/table>\n    <script type=\"text\/javascript\">decorateTable('product-attribute-specs-table')<\/script>\n","name":"COnf Atr 1","price_html":"\n\n                        // code ommited for brevity
                        confData.textNotAvailable = "Choose previous option please...";
                        confData.mediaUrlMain = "http://dev.domain.local/amconf/media/index/id/13/";
                        confData.oneAttributeReload = "1";
                        confData.imageContainer = ".product-img-box";
                        confData.useSimplePrice = "1";
                </script>

I was unable to disable this setting from the extensions settings on the admin panel. I had to comment out line 62 of

app/code/local/Amasty/Conf/Block/Catalog/Product/View/Type/Configurable.php

 //'attributes'        => Mage::app()->getLayout()->createBlock('catalog/product_view_attributes', 'product.attributes', array('template' => "catalog/product/view/attributes.phtml"))->setProduct($simple)->toHtml()

I don't think this is a good solution though as the extension is grabing this data to swap simple product attributes with the parent configurable product attributes on the product view page. I think the whole issue arises as the module is not compatible with Magento 1.9 rwd theme which puts the additional information in a tab.

You could customize the template catalog/product/view/attributes.phtml. Copy it to your theme from base/default if it isn't there yet and include what you need.

For better maintainability, I'd recommend to just add $this->getChildHtml('my_child_alias') to the template and define child blocks in the layout (i.e. layout/local.xml of your theme:

<reference name="product.attributes">
    <block type="core/template" name="my.custom.product.block" as="my_child_alias" template="my/custom/template.phtml" />
</reference>
