Our file manager on the product site fails to upload any files. When we click the 'upload' button we are getting the following error:

 

We have never had this problem before.

 

On 3rd party applications such as Catalook, next to the file uploader we get the following error:

Error: File not found (Select [Synchronize Files] at the Admin / File Manager page with [Recursive] option turned off and on)

We did try this many times, but with no results.

We deleted all the entries from the dbo.Folders table and then run the recursive sync but still, no luck.

The NTFS permissions are set properly.

Any ideas?

Hello Matthias, 

Well, I'm logged on as Host and Admin but still get the same results. I can browse the files under File Manager but under other modules I can't. Also, I can't upload any files under Admin/File Manager, but under Host/File Manager I can do anything and works fine.

I have tried these:
