If I activate iphone theme on www.faceroam.com then under any photo I read htis error in homepage:
Notice: la funzione è deprecata. in /usr/local/ndn/web/oneclicks/zenphoto/zp-core/zp-extensions/deprecated-functions.php on line 376
How to patch it?

The theme author of the iPhone theme will need to update it eventually. In the mean time you can disable the error message in the options of the deprecated_function plugin.
