XML Parsing Error on connector.aspx?command=Init

There is definitely something there changing the output sent by the CKFinder connector. It could be a theme, but usually it just appends HTML to the output, and it looks like we have something else there.

It could be also that, somehow, the web server is gzip compressing the output, but without sending the compression headers (Content-Encoding: gzip).

Anyway... I think the best way to understand it is by precisely looking at the server response headers and body. For that, I would recommend using IE and Fiddler.

If you want us to take a look at it too, you can use "File > Save > Session(s) > in ArchiveZip" in the Fiddler menu. It will generate a .saz file, which you can attach here.

It's not only for IE, you can use it with any other browser. Although it might not be automatically set up it's very easy to do so.

Hello:

I am also connecting it to the Blogengine and it gives me the same error.

I tried two logical solutions:

1) I Disabled the the Compression method nly for the connector.aspx page:

<script runat="server">
protected override void OnLoad(EventArgs e)
{
Request.Headers["Accept-encoding"] = null;
base.OnLoad(e);
}
</script>

But then it gave me the error:
"XML request error: Internal Server Error (500)
Do you want to see more info?"

After I pressed the OK button a huge html was presented to me within the alert message box.

2) I disabled the compression system for the entire blog. I went to the BlogEngine.Core\Web\HttpModules\CompressionModule.cs and chanded the function IsEncodingAccepted to:

private static bool IsEncodingAccepted(string encoding)
{
return (false);
}

But when I activated the CKFinder it gave me the message "Unknown error" (the message box was from the CKFinder component itself and not the browser alert).

---

So basically, how do I fix it?
I want the compression system and I want the CKFinder to work.

Thanks, Israel Sapir

Check CKFinder 2.0 - it should display a more user friendly error message instead of an alert box.

Also please try the debug mode: http://docs.cksource.com/CKFinder_2.x/D ... leshooting

Im having exactly the same problem in one of my sites. The ckeditor, ckfinder, bin folders and web.config are exactly the same... but in one of the sites, altough ckeditor works perfect and I have all the ckfinder extensions on ckeditor, when I click "browse button" i get like a bad encoded XML response and I get an exception thrown by ckfinder with an unlegible message (with a "system error" as window tittle). It happens in every browser.

Please, if you have any idea, I've wasted like 20 hours sniffing headers, code, recompiling in ton of ways, cleaning temp files, caches, etc and the result is always the same... one site works perfectly with ckfinder and other not.

Im using asp.net 4, vs2010 and the integrated web development server.
The problem is here, but i cant read or decode the response with fiddler, while I can decode it perfectly in the site that works:

one day later (lol)... the gzip functions that I had in global.asax had problems with the response so I couldnt read the message. Now the error is:

An exception of type 'System.MethodAccessException' occurred in CKFinder.DLL but was not handled in user code

Additional information: Attempt by security transparent method 'ImageManipulation.Quantizer+Color32..ctor(IntPtr)' to access security critical method 'System.Runtime.InteropServices.Marshal.PtrToStructure(IntPtr, System.Type)' failed.

Assembly 'CKFinder, Version=4.0.0.945, Culture=neutral, PublicKeyToken=579e7adc719a1423' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.

And just by adding this under system.web in web.config... everything works with this site

<trust       legacyCasModel="true"     level="Full" />

I think that Medium trust should be fine as well.

I´ve got a mistake, i ´ve got this: <trust level="Medium" processRequestInApplicationTrust="true"/>
and a i have this Error:
Error de servidor en la aplicación '/'.
Excepción de seguridad
Descripción: La aplicación intentó realizar una operación no permitida por la directiva de seguridad. Para otorgar a esta aplicación los permisos necesarios, póngase en contacto con el administrador del sistema o cambie el nivel de confianza de la aplicación en el archivo de configuración.

Detalles de la excepción: System.Security.SecurityException: Ese ensamblado no permite llamadores de confianza parcial.

Error de código fuente:

El código fuente que generó esta excepción no controlada sólo se puede mostrar cuando se compila en modo de depuración. Para habilitarlo, siga uno de estos pasos y, a continuación, vuelva a solicitar la dirección URL:

1. Agregue una directiva "Debug=true" en la parte superior del archivo que generó el error. Ejemplo:

<%@ Page Language="C#" Debug="true" %>

o:

2) Agregue la siguiente sección al archivo de configuración de su aplicación:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Tenga en cuenta que esta segunda técnica hará que todos los archivos de una aplicación dada se compilen en modo de depuración. La primera técnica hará que sólo ese archivo en concreto se compile en modo de depuración.

Importante: al ejecutar las aplicaciones en modo de depuración se provoca una sobrecarga de memoria o rendimiento. Debe asegurarse de que la aplicación tiene deshabilitada la depuración antes de implementar en el escenario de producción.

It looks like it was your post, right?

Do you have this problem with CKEditor.NET? (Note that you have replied to a topic on a CKFinder forum)
If it is indeed a problem with CKEditor.NET, please redownload CKEditor.NET control, we have fixed this problem ~4 days ago: http://dev.ckeditor.com/ticket/7276
