symlink not accessible via http

Hi, I have a hosted website on a linux server with apache. I created a symlink from one directory to another so that users can access the same files from 2 different directories. command : symlink ('testorig', 'test1'); When in my filemanager (Plesk) I click on the test1 directory I get in the testorig directory and the link works fine. When I access via http the file ..../testorig/index.htm, I see it, but when I use ..../test1/index.htm I get : Forbidden You don't have permission to access to this document on this server. What is wrong? Can someone help me? thanks, Boeli
