When I try to use the author alias field I get the following error above the article.Notice: Undefined property: stdClass::$profile in /home/yakangl1/public_html/components/com_k2/models/item.php
on line 281

Wow K2 support sucks, you never get a reply on anything! What other solutions are there? Should I just go back to using the standard Joomla articles?

Hi. Fixed for the next release. You can temporarily set error reporting to simple or none to stop getting this notice. Thanks for reporting.
