Error in Phoca Gallery display

[waynenort]

I've installed a fresh copy of Phoca Gallery successfully and create a new Phoca webpage via the main menu as a Category List Layout. I haven't uploaded any images yet, but when I open the new Phoca webpage I page seems to display OK, but I also get this error:
Warning: Invalid argument supplied for foreach() in /home/saintsbc/public_html/components/com_phocagallery/models/categories.php on line 158

What could be wrong?

Thanks, Wayne
