Session hash is NULL ...?

Hello,

I have problem with ezmultiupload when trying to upload any files, as so many others... After progress bar goes up to 100%, I can see frames (simply empty bordered rectangle) instead of the images (one instead of each image) and inside each frame I see simply "Error access denied" without any debug below.

This is with administrator account, so is not a problem of permissions on ezmultiupload module, etc. All install notes followed, this extension was working previously here, so this comes down to the latest changes in it OR in ezp version (4.1 & 4.1+). Also, I have already check up with the issue tracker and tested with patches and suggestions on the problem with missing function defined for the views of extensions. Unfortunately this was not of help, or at least I got no positive results.

Error log is giving me query error for duplicate entry each time I get to the 100% progress bar, and system is trying to insert into ezsession table data for anonymous user (??).

After debug of upload script, I came down to the fact that I get correct user object (my login at the moment of upload), but the user session hash is NULL as default set into the session class of ezp (and, of course, result from eZSession::getUserSessionHash() is also NULL). Hence, this sends empty value into the upload params that are being feed from upload.php into the upload template and the js implementation there.

Is this correct (which I do not thing is), and what might have cause it?? Is it possible that this is the problem that causes my images to be changed into "Access denied" message frames? Any help be possible on this?

Thanks!
Deni
