GS3.1.1 filebrowser issues

[andyash]

Replace in filebrowser.php

Code:

<script type='text/javascript'>
    function submitLink($funcNum, $url) {
        if ($funcNum!=""){
            if(window.opener){
                window.opener.CKEDITOR.tools.callFunction($funcNum, $url);
            }
        }
        <?php if (isset($_GET['returnid'])){ ?>
            if(window.opener){
                window.opener.document.getElementById('<?php echo $returnid; ?>').focus();
                window.opener.document.getElementById('<?php echo $returnid; ?>').value=$url;
            }
        <?php } ?>    
        <?php if (isset($_GET['func'])){
        $func = @$_GET['func']; ?>
            if(window.opener){
                window.opener.<?php echo $func; ?>('<?php echo $returnid; ?>');
            }
        <?php } ?>    
        window.close();
    }
    </script>

with the patch given in http://get-simple.info/forum/post/28066/#p28066

Code:

<script type='text/javascript'>
    function submitLink($funcNum, $url) {
        <?php if (isset($_GET['returnid'])){ ?>
            if(window.opener){
                window.opener.document.getElementById('<?php echo $returnid; ?>').value=$url;
            }
        <?php } else { ?>
            if(window.opener){
                window.opener.CKEDITOR.tools.callFunction($funcNum, $url);
            }
        <?php } ?>
        window.close();
    }
    </script>

makes the WYSIWYG editor work fine and I can import images from my main editor as well as the one added through Custom Fields plugin.

Any ideas why the new install of GS3.1.1 works fine but updating a GS3.1 site by replacing the admin folder makes filebrowser.php act weird?
