Purity IV error with default content

quasiman

In local dev, I installed the Joomla blog content and then installed Purity IV. Nothing else has been done to the site. Navigating through the content, I came across this error:
http://localhost/joomla/?option=com_content&view=author&layout=author&id=600

Warning: Undefined property: Joomla\Component\Content\Site\View\Author\HtmlView::$category in E:\xampp\htdocs\joomla\templates\ja_purity_iv\html\com_content\author\author.php on line 52

Warning: Attempt to read property "title" on null in E:\xampp\htdocs\joomla\templates\ja_purity_iv\html\com_content\author\author.php on line 52

Hello

It seems to be a PHP warning, you can open the associated file: E:\xampp\htdocs\joomla\templates\ja_purity_iv\html\com_content\author\author.php

Look for the line 52:

<span class="subheading-category"><?php echo $this->category->title; ?></span>

change it to:

<?php if (isset($this->category) && !empty($this->category->title)) : ?>
    <span class="subheading-category"><?php echo htmlspecialchars($this->category->title, ENT_QUOTES, 'UTF-8'); ?></span>
<?php endif; ?>

And let me know how it goes.
