If you are getting this error there is something serious wrong with your installation. This function is defined in functions-basic.php which is loaded always.
Just to be sure I did a complete new install: downloaded the 1.2.2. files again, deleted ALL the files from my server except the zp-config.php file and the album and cache folders, but still I get this error message. And ofcourse I ran setup.php again with no error messages...
