Just deployed a CakePHP on a domain running PLESK and dismayed by the fact that your screen is over-flowing with warning about open_basedir restriction in effect? Fear not, the solution is straight forward (if a little frustrating to track down!)
The problem is caused by this line (line 69, in CakePHP 1.2.0.6311) in /app/webroot/index.php:
ini_set('include_path', CAKE_CORE_INCLUDE_PATH . PATH_SEPARATOR . ROOT . DS . APP_DIR . DS . PATH_SEPARATOR . ini_get('include_path'));
Yep, the simple ini_set command – the clues should start coming in thick and fast that ini_set is causing the problem due to the fact taht open_basedir complains about paths with :’s in their structure. (:’s being the delimiter for automatically included paths). To fix the problem you can either remove the if logic that calls “function_exists(‘ini_set’)”, or, if you prefer to fix things the corret way, modify the line to remove the final stub:
ini_set('include_path', CAKE_CORE_INCLUDE_PATH . PATH_SEPARATOR . ROOT . DS . APP_DIR . DS);
Good luck, hope that saves someone a headache! 
That has seriously saved so much time for me – it got rid of all of those errors..but… there’s always a but..
I am getting these errors still..

I am not sure – but I am trying to set up a sub-domain not a primary domain with cake. It’s plesk 7.5.4 that I’m trying to use as well.
Do you think it has anything to do with this? http://www.experts-exchange.com/Software/Server_Software/Web_Servers/Apache/Q_21788041.html?sfQueryTermInfo=1+apach+cgi+httpd.conf+plesk+rail+rubi+vhost
My head is about to explode
thx mate, very very useful. Just saved me an aspirine.
Thanks a lot for this tip. I am new to CakePHP and Plesk.
This tip has been of great help for me!
Kind regards, Christine
The fix didn’t work for me, but I am not using Plesk. I have a feeling this is going to waste my whole day.
