No access of subpages+No access Backend/ControlPanel & Confi

[Passat2007]

Hi all,
we are running Joomla for a small sailing club. Yesterday, after 5 months without any problem, we had following problem.
1 hour before the problem occured, I changed the module position of 'DJ-Imageslider' component and its arrangement on the starting page. And I exchanged the pictures the slider should show. I do not think that is of importance - just for a complete diagnosis. Meanwhile I could deactivate the slider.

1. All subpages can't be accessed - I get error 404, while the header and top menu are shown.
2. Login at the administrator page is causing following failure message if accessing the control panel (default 1st page for Backend access):

Code: Select all

Fatal error: require_once(): Failed opening required '/homepages/24/.../components/com_jce/editor/libraries/classes/editor.php' (include_path='.:/usr/lib/php5.4') in /homepages/24/.../administrator/components/com_jce/includes/loader.php on line 49

Meanwhile I could access the login as Superuser, because it opens the COMPONENT Menü (maybe, because I was logged in recently in that component menu). AFter that I have seen , that only the
SYSTEM ---> CONTROL PANEL and
SYSTEM --> CONFIGURATION
is causing the fatal error as seen above after 1st log in. ALL other menus seem to be ok and can be accessed.

Any idea, what I can do, to get rid of this problem?

Any comment is appreciated...

PS: Line 49 , Loader.php shows:

Code: Select all

 if (!isset($paths[$keyPath])) {
            // set base as Component root
            $base = JPATH_COMPONENT_ADMINISTRATOR;

            switch ($key) {
                case 'editor':
                    $base = JPATH_SITE . '/components/com_jce/editor';
                    break;
                case 'admin':
                    $base = dirname(dirname(__FILE__));
                    break;
            }

!LINE 49!            $rs = require_once($base . '/' . implode('/', $parts) . '.php');

            $paths[$keyPath] = $rs;
        }

        return $paths[$keyPath];
