Question

After upgrading to 1.7 (all on a dev server thankfully!) I am getting the following error logs for the clients custom theme:

Theme is working fine on a 1.5 installation, but as the theme was made by someone else (and they installed the old version, I cannot be certain they didn’t tinker with any core code etc

Googling found results for “Invalid method Mage_Catalog_Block_Navigation::renderCategoriesMenuHtml” but not “renderCategoriesAndChildrenMenuHtml”. I thought it may have been a custom function, but I found it in the core code. Totally stumped on this one!

Answer 1

The default theme of Magento 1.5.0.0 calls the renderCategoriesMenuHtml and block contains only the function renderCategoriesMenuHtml. In your case, or someone corrected the core files, or a module that rewrites the Mage_Catalog_Block_Navigation.

One possible solution is to replace function renderCategoriesAndChildrenMenuHtml to renderCategoriesMenuHtml in file app/design/frontend/p365_mydomain/default/template/catalog/navigation/left.phtml or use default template for navigation/left with code:

<?php if (!Mage::registry('current_category')) return ?>
<?php $_categories = $this->getCurrentChildCategories() ?>
<?php $_count = is_array($_categories)?count($_categories):$_categories->count(); ?>
<?php if($_count): ?>
<div class="block block-layered-nav">
    <div class="block-title">
        <strong><span><?php echo $this->__('Browse By') ?></span></strong>
    </div>
    <div class="block-content">
        <dl id="narrow-by-list2">
            <dt><?php echo $this->__('Category') ?></dt>
            <dd>
                <ol>
                <?php foreach ($_categories as $_category): ?>
                    <?php if($_category->getIsActive()): ?>
                    <li>
                        <a href="<?php echo $this->getCategoryUrl($_category) ?>"<?php if ($this->isCategoryActive($_category)): ?> class="current"<?php endif; ?>><?php echo $this->htmlEscape($_category->getName()) ?></a> (<?php echo $_category->getProductCount() ?>)
                    </li>
                    <?php endif; ?>
                <?php endforeach ?>
                </ol>
            </dd>
        </dl>
        <script type="text/javascript">decorateDataList('narrow-by-list2')</script>
    </div>
</div>
<?php endif; ?>
