XML request error (no Response text)

I've the same problem, however only in IE7.
I do not have the problem on the demo page ( http://www.fckeditor.net/demo )

Some details:
Browser: IE7 and IE6 ( not in Firefox, didn't test other then IE and FF )
Connector: PHP



---[ edit ]-------------------------

After some debugging I found that some filenames are not properly encoded.
To temporarily fix this, I've changed: editor/filemanager/connectors/php/commands.php:83
From:

$aFiles[]    = '<File name="' . ConvertToXmlAttribute( $sFile ) . '" size="' . $iFileSize . '" />';     

$aFiles[]    = '<File name="' . ConvertToXmlAttribute( rawurlencode( $sFile ) ) . '" size="' . $iFileSize . '" />' ;     

This doesn't fix the problem because the broken files won't show with this hack, however the XML is valid, so other files can be selected and you don't get that pretty error.

I've wrote a small script which you can use to check if that is the case for your XML response. should you have troubles figuring out what it does drop me a line.

<?php

 * defaults set to the php connector, using your images dir in: domain.com/

$url    = 'http://www.domain.com/FCKeditor/editor/filemanager/connectors/php/connector.php?Command=GetFoldersAndFiles&Type=Image&CurrentFolder=%2F';

$str    = file_get_contents( $url );

//- no config needed below this line -\\

$len    = strlen($str);
$cor    = array();
$cols    = strlen($len);

echo "\n\nCharacter`s found:\n";
for ($i=0; $i < $len; $i++ ) {
    $ord    = ord( $str[ $i ]);
    if (($ord < 32) || ($ord > 126)) {
        $cor[ $i ]    = $str[ $i ];
        printf("[%0". $cols ."d] <b>%s</b>   ord(%d)\n", $i, $str[ $i ], $ord );
    }
}


if ( count($cor)>0 ) {
    echo "\n\nPhrases with corrupt XML:\n";
    foreach ($cor as $index=>$fubar) {
        $start    = max(0, ($index-20));
        echo substr( $str, $start, 40 ) ."\n";
    }
} else {

}
        

I'm getting the same problem and also a 501 error when trying to post so I'm attaching my post as a txt file. It contains all the information on my platform and settings that I hope will help debug this issue.

The forums error I am getting is
Method Not Implemented

POST to /forums/posting.php not supported.
Apache/2.2.0 (Fedora) Server at http://www.fckeditor.net Port 80

I thought it might because there was some PHP in the post so wrapped it in [code] but still the error.

This error occurs in IE7 if the php-connector find some files with special-chars:
For example, if you use an & (ampersand) or a german - so called - "Umlaut" as ä,ö,ü HTML: ä &öuml; ü

If i find the time, i will post a solution. Shuold only be a small change in upload.php...

I think, it is solved. Just change line 209 in commands.php:

from:

$sFilePath = $sServerDir . $sFileName ;

to:

$sFilePath = $sServerDir . preg_replace('/[^a-zA-Z0-9\. _-]/','',$sFileName) ;

every char not matching to the regular expression will be removed. You may add some chars to the expression, if you really need it...
But i think most users could live with this solution
