Suite error after upgrade to 4.0.3 from 4.0.1
 

In firefox (only so far), I get the following at the top of my cms page. And it will sometimes not load the page at all and only display that, other it loads but that message is at the top above everything.

Code:
Warning: Invalid argument supplied for foreach() in [path]/packages/vbcms/widget/recentcmscomments.php on line 319
Any ideas please?
