Permission Issues

Have installed the most recent version.

Set the following permissions on the SuiteCRM directory(Linux):
sudo chown -R www-data:www-data .
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload config_override.php

Unfortunately, I am installing on Hostgator and am unable to execute a chown even thought I have SSH access (it seems it is a jailed SSH which does not allow for a chown.

At this point int time, the user and group ID has been set to the account ID. Is this good enough?
All other permission settings are as per recommended

Installation completes with a warning.

And Suite CRM runs, however I keep getting undefined warnings or errors. It pops up very frequently.

Appreciate any help in this matter.
