I thought I'd post this as an announcement as it seems to be popping up a lot. There is a bug in PHP 5.3.0 affecting the parse_ini_file function:
http://bugs.php.net/bug.php?id=49172
Since Xataface relies heavily on this function for its ini files, Xataface will not work with PHP 5.3.0.
Solution:
Upgrade to PHP 5.3.1 or downgrade to PHP 5.2.x
