hi

with Zenphoto version 1.4.3.5 [11059], I have a lot of this warning in my debug log :
Backtrace: WARNING: Invalid argument supplied for foreach() in .../zenphoto/zp-core/zp-extensions/zenpage/zenpage-class-news.php on line 144 ZenpageNews->categoryIsVisible called from Zenpage->getArticles (zenpage-class.php [263]) from getNumNews (zenpage-template-functions.php [205]) from include (inc_header.php [285]) from include (pages.php [1]) from include (index.php [5]) from index.php [92]
do you have an idea about this message ?

It appears a bug if you call this function on an article which is in no categories.

I have a look on articles of my website.
All of them have at least one categorie.

The problem will occur if any SQL error occurs on the query, so maybe some other thing was in error.
