    <p>Your "category" object might be actually <em>null</em> in Chrome, i.e., did you call <code>Mage::register</code> on <code>current_category</code>?</p> <p>Check the URL and call that opens that page, or verify it is not a session issue (e.g. you have data in the Firefox session, but not the Chrome one).</p> <p>Depending on how you arrived at that page, you might be in an area where <code>current_category</code> is not (yet?) set by <code>CategoryController::_initCategory()</code>, because for example the category is not present in the URL. See <a href="https://stackoverflow.com/questions/6264514/any-reason-why-mageregistrycurrent-category-would-return-null">this answer</a> for some more details. Suppose now that the category is saved in the session and you made several page hits with Firefox. Now the Firefox session <strong>does have</strong> a cached category available, and when you hit the troublesome cache in Firefox, you see the cache. Then hit that same page with Chrome which has no session or cache available (yet), and that gives you an error.</p> <p>You may want to wrap the call with some fallback code, to sidestep the problem and not use the category code unless there is indeed a category available:</p> <pre><code>// Here you might get NULL $current_category = Mage::registry('current_category'); // If category is **not** NULL, *and* is Showroom, then... if (($current_category) &amp;&amp; ($current_category-&gt;getName() == 'Showroom')): </code></pre> <p>Depending on where you are in the code, you can check more ways of getting the category; see <a href="https://stackoverflow.com/questions/10282847/magento-registry-and-current-category">this answer</a> for details.</p>

    1. COhi! sorry, what did you mean by "did you call Mage::register on current_category?" this: $current_category = Mage::registry('current_category');

    3. CO`current_category` is *not* automatically set in all pages. Where it is not, you either set it yourself (if it is really needed), or it will be NULL -- giving the error you have. I'll expand my answer, though.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
