Hello

I am having a problem with File Sharing. I've never used it before and now

When I try to create a folder or upload a file a get the folloing error :

Unable to create folder: internal WebDAV service error. Error code: 500. Contact the server administrator to resolve this problem.

How can I fix it?

Thank you very much

PS: I am using Plesk 10.4.4 #41

Unfortunately nothing helpful in the logs files...

The only I found at the access log is

[12/Aug/2012:09:47:29 +0000] "POST /smb/file/create-folder/ HTTP/1. 1" 200 184 "https://(my domain):8443/smb/file/index/type/private" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv: 14.0) Gecko/20100101 Firefox/14.0.1"

I did the uprgade to version 11, but same problem.
