I have a problem with posting comments to the blog. When I try to do this, it says that "a problem has occured while adding the comment". I have set the comment directory as "httpdocs/blog/comments" with permissions 777. Do I only have to set the 777 permissions on this comments directory, or also on the blog or httpdocs directory? Also I can't get access to the admin directory. When I entre the username and password, it says that "the comment-directory on the webserver is not accessible". Can you help me out?
