Home-Template with PHP8: Date Problem

Hello,

I recently purchased the template and now found that there is a problem. This line in the blog_item.php file is responsible for this.
How can I fix these?

Deprecated: strtotime(): Passing null to parameter #1 ($datetime) of type string is deprecated

|| ((strtotime($this->item->publish_down) < strtotime(JFactory::getDate())) && $this->item->publish_down != JFactory::getDbo()->getNullDate())) : ?>

Hello,

Please try replacing the file /templates/homes/html/com_content/category/blog_item.php with the attached file (unzip it first).

Regards,
Milos
