Error in Module

Got an email from my server:

synchronizeProfiles(): exec(/usr/local/bin/php -f refresh.php 0 1 ) returned 255

Thats funny so did I. Except mine said...

Fatal error: Call to undefined function getprofileinfo() in /home/public_html/xxx/inc/membership_levels.inc.php on line 423

Module error: synchronizeProfiles(): exec(/usr/bin/php -f refresh.php 0 1 2 3 ) returned 255

The 0 1 2 3 bit refers to the 4 users that aren't getting synchronised (the number seems to echo the number of my test users), i guess. And I get an email everytime I refresh modules. I have tried to chase this through the code and can't. the paths that it describes exist ok.

I could really do with some help on this...

I also noticed that all of my pages are staying in cache on all three browsers that I'm using - so every change to an admin entry only shows up if i refresh the page - causes real havoc with the form validation pic thngy.
