image manager issue

[macko]

Hello,

I installed CMS 1.4.1 yesterday.
When I try to use the image manager I get the error:

Not Acceptable
An appropriate representation of the requested resource /lib/filemanager/ImageManager/images.php could not be found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.


Also in admin under content>>pages I get a popup error box

Error: the xajax Javascript file could not be included. Perhaps the URL is incorrect?
URL: http://www.site.com/lib/xajax/xajax_js/xajax.js


i tried reloading the file. 
I get the same error when trying to access through a browser. 
I tried changing the permissions.
Is this a path problem? I can't figure out where to change the path to this.  There is no .htaccess file in my lib directory.

Under system information I have -

PHP Open Basedir (open_basedir):

/home/jpmcont/:/usr/lib/php:/usr/local/lib/php:/tmp Caution
Open basedir restrictions are in effect. You may have difficulty with some addon functionality with this restriction


I'm not sure if all this is related?

Server info is:

Apache version 1.3.41 (Unix)
PHP version 5.2.5
MySQL version 4.1.22-standard

I do not seem to have access to the php.ini file.

thanks in advance for any help.
