Error in trying to create a new page

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Click on "New Page" link
2. Enter a new page name and click on "Create page" button

What is the expected output? What do you see instead?
Expected output: Ability to create a new page.
Instead: I get this error:

Warning: fopen(../index.php) function.fopen: failed to open stream:
Permission denied in /root/cms/new-page.php on line 178

Warning: fwrite(): supplied argument is not a valid stream resources in
/root/cms/new-page.php on line 179

Warning: fclose(): supplied argument is not a valid stream resource in
/root/cms/new-page.php on line 180
not found!

What version of the product are you using? On what operating system?
1.13
Client: Windows XP, Firefox 2.0.0.14 browser
Server: Linux, with PHP 5

Please provide any additional information below.
I am sure this is a permissions problem. I just don't know where. The file
new-page.php and the /cms folder has read/write (666) permissions. Even
changing this to 777 did not correct the problem.

mig234, the CMS (PHP) also needs write permissions in the root folder, in order 
to
save the live copy of your page there. It's ../index.php (i.e. root/index.php, 
when
called from root/cms/) that's causing the error.

Also check that root/cms/includes has 755 or 777 set.
