CakePHP permission error

I am a novice developer. I outsourced this script. I have no idea why I am getting this error. Script was previously on shared hosting, now on media temple private server. I did have to change permissions from 755 to 777 to get anything to show up. Any hints, or a reference would be appreciated. Thank you.

what are the permissions and ownership on the folder /var/www/vhosts/arizonadealz.com/httpdocs/app/tmp/cache/persistent/cake_core_core_paths ? it would need to be writable by the web-server.

Sorry to hear about the issues you were having with your server. If you want us to take a look at it, I suggest opening up a Support Request so we can further troubleshoot the issue. Are you on a (dv) or a (ve)?
