Have set up 5.2 open source on our webserver we are running php 5.2 and all machines with win xp sp3.

We are having problems with email collection, i have narrowed it down to file permission settings in the config file after i changed the defualt settings to be 777 on folders and files and reinstalled sugar to a new directory i received much less errors in the log (kept getting file doesnt exist or permissions are wrong) however i am still getting a couple of errors whcih appears to be stopping email collection.

The error log reads just one error now:
[03-Jan-2009 11:13:00] PHP Warning: Invalid argument supplied for foreach() in /home/amber/public_html/sugar/modules/InboundEmail/InboundEmail.php on line 5974

Line 5974 in InboundEmail.php begins:
foreach($ret['retArr'] as $msg) {

I have also found that in the folder cache>module permissions are set to 770 and i have tried to change it to 777 however i am unable, i have noticed this folder is basically locked i cannot delete it, change it or open it .

Have i got some php.ini issues or is it an error that can be fixed.
