[drupal-support] Upgraded to 4.5.4

[Dan Romanchik]

I just upgraded to 4.5.4 from 4.4.2, and while the upgrade 
went pretty smoothly, I'm now getting the error message:

warning: Invalid argument supplied for foreach() in [[path 
to Drupal]]/www/themes/arrow/arrow.theme on line 117

when I first access the site. The home page displays 
correctly, and if I refresh the page or click to a second 
page, the error message goes away.

Any ideas what's wrong?

Thanks, Dan
