Fatal Error uploading an image

When I try to upload an image into the wysiwyg on all pages, this is the error I get:

Warning: require_once(lib/menus/default/uploadForm_functions.php): failed to open stream: No such file or directory in /data/10/0/103/119/918771/user/939622/htdocs/cmsAdmin/lib/menus/default/wysiwygUploads.php on line 3 Fatal error: require_once(): Failed opening required 'lib/menus/default/uploadForm_functions.php' (include_path='/data/10/0/103/119/918771/user/939622/htdocs/cmsAdmin:/data/10/0/103/119/918771/user/939622/htdocs/cmsAdmin/3rdParty:.:/usr/services/vux/lib/php') in /data/10/0/103/119/918771/user/939622/htdocs/cmsAdmin/lib/menus/default/wysiwygUploads.php on line 3

------------------------------------------

Here is the code from the top of the page:
<?php header('Content-type: text/html; charset=utf-8'); ?>
<?php


// load viewer library
$libraryPath = 'cmsAdmin/lib/viewer_functions.php';
$dirsToCheck = array('/data/10/0/103/119/918771/user/939622/htdocs/','','../','../../','../../../');
foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

// load records
list($home_improvementRecords, $home_improvementMetaData) = getRecords(array(
'tableName' => 'home_improvement',
'allowSearch' => '0',
'limit' => '1',
));
$home_improvementRecord = @$home_improvementRecords[0]; // get first record

// show error message if no matching record is found
if (!$home_improvementRecord) { dieWith404("Record not found!"); }

?>

What could be causing this?

Thanks.
