I loaded the mod_dav and mod_dav_fs on my httpd server. An then I followed the tutorial for set up webdav in eZ Publish here : http://ez.no/doc/ez_publish/technical_manual/4_0/features/webdav/setting_it_up
If I connect to my website via webdav I see the siteacces folder but when i double click on the folder I obtain an error message : <b>Error: HTTP Error: Not Found</b>
