I recently noticed two errors appearing on the Home page of my domain: lr-roofing.com.

Latest from
Notice: Undefined property: stdClass::$author in /home/lrroofin/public_html/components/com_k2/templates/default/item.php on line 435

Notice: Trying to get property of non-object in /home/lrroofin/public_html/components/com_k2/templates/default/item.php on line 435

I was able to suppress them by choosing 'Hide' for one of the options in my article Item page. To do this I selected System | Control Panel in the menu bar, then chose 'Items'. In the K2 Items page I selected the Title: 'L&R Roofing'. In the K2 Edit Item page, in the 'Item view options' section under 'Author options', I toggled the 'Latest items from author' options from 'Inherit from category' to 'Hide'.

Could you please let me know why I'm suddenly getting these errors and whether thre is there a way to eliminate them when the option is set to either 'Inherit from category' or 'Show'?
