Can't open pages in content after upgrade

[kingmangu]

Hi,

After I upgrade my website from version 1.11.9 to 1.11.10 I am able to log in to the admin panel but I can't open the pages in the content. I get this error message:
------------------
Warning: include_once(../lib/classes/class.admintheme.inc.php) [function.include-once]: failed to open stream: No such file or directory in /home/content/22/6068222/html/mysite/mysite/admin/listcontent.php on line 30

Warning: include_once() [function.include]: Failed opening '../lib/classes/class.admintheme.inc.php' for inclusion (include_path='.:/usr/local/php5_3/lib/php') in /home/content/22/6068222/html/mysite/mysite/admin/listcontent.php on line 30
Output has already been sent to the browser at /home/content/22/6068222/html/mysite/mysite/admin/listcontent.php:30. Please make sure the command $xajax->processRequest() is placed before this.
------------------

Let me know if there is a PHP problem o something else. Your help will be very appreciated. Thanks!

I don't know how you upgraded, but if you used the diff, that specific file '/lib/classes/class.admintheme.inc.php' is not even touched/overwritten.

Start to check if it's there.

I updated using FTP, The file is there but it acts like there is not there.

You most likely have a permissions/ownership problem.
You should try, if at all possible, an alternative upload method. Even using CPanel own File Manager to upload the full archive and expand it there.
