Unknown error on image upload (.NET version)

Hello,

I have the .NET verion of 1.3 ckfinder but connected to it via FCKeditor. I'm working off a development machine (XP sp3) and a production server (server 2003). .Net 3.5 on both machines. I've verified that IUSR_<MachineName> had modify on my userfiles directories. On my dev machine, CKFinder works as expected. On the production computer, I can browse the files and images perfectly fine, put when I click on the upload button I get "unknown error".

I've seen references to a "Debug" option, but can't seam to find that in the config.aspx file and If I add it, it's invalid for the namespace. Both machines run the website from a root level, not sub directories, so the basepath on both is just /ckfinder/

Screen shot attached.

Re: Unknown error on image upload (.NET version)

Hi,

It looks to me like a permission issue.
To enable debugging, you should build CKFinder in a debug mode.

Unfortunately, to get rid of the "Unknown error" message during file uploads, you should do some extra manual work.
Please remove the following code:

catch
{
   iErrorNumber = Errors.Unknown;
}

Re: Unknown error on image upload (.NET version)

it might be also server full or there is no space left in your host.

Re: Unknown error on image upload (.NET version)

for what it is worth.. this is just what happened to me with "unkown error" and how i made it go away...

added ASP_NET as a user to the /userfiles/ folder .. i am thinking that is necessary because its on my local machine right now

perhaps a totally unrelated issue.. but who knows...

turns out i was also getting routed to my friendly error page on startup of the web application, so i added

ASP_NET as a user to one the databases the website uses..

problem is gone..

Re: Unknown error on image upload (.NET version)

Re: Unknown error on image upload (.NET version)

I did what wiktor said and re-compiled the DLL without that catch statement. I also installed Fiddler and ran it to capture requests. I tried to upload a file and watched the requests. Fiddler did not show anything other than 200 (OK) and the CKFinder now just says "Upload in progress, please wait..." without popping the Unknown error.

Do you have any other debugging tips so I can actually see where it breaks?

Re: Unknown error on image upload (.NET version)

What's the response sent by the server to the last command issued? (should be a POST to upload the file)

That text is the error message, but now you have to read it in Fiddler, not in CKFinder.

Here is the last header. Since I don't know really how this thing works, I cannot debug very well.

Re: Unknown error on image upload (.NET version)

As you said, those are the headers, but the interesting part is the content of the response. Select the TextView pane of the bottom Inspector (response) and check what does it says.

Re: Unknown error on image upload (.NET version)

So sorry about that. Fiddler provides so much info and I'm just overwhelmed with all the data.

Here's the header:

POST /ckfinder/core/connector/aspx/connector.aspx?command=FileUpload&type=Gallery%20Images&currentFolder=%2F&hash=ced1c5fa28df0178 HTTP/1.1

Re: Unknown error on image upload (.NET version)

This IS a permissions issue.

Thanks to all those who posted above. I set user group "Everyone" (IIS 6) to Modify, reset IIS and it works. Now to figure out exactly which users need write permissions as the "Everyone" group cannot be used as a permanent solution!

Re: Unknown error on image upload (.NET version)

Try to grant the extra privilege just to the Aspnet account, as well as the IUser_ (machine name) account: the internet guest account
