This is a FrontPage bug. When adding a browse-only user, you need to add the user as browse-author, apply changes, and then remove author permissions.
This can happen when you publish to a server that has not had FrontPage Server Extensions installed.
FrontPage allows you to publish via FTP if FrontPage extensions have not been installed on your server. However, the base directory for FTP publishing is your home directory, which is one level below the www directory that the web server uses to serve pages. You need to add "/www" to the publishing location when publishing via FTP.
The preferred method is to have FrontPage extensions installed and to publish via HTTP.
Your account is over its disk quota. You need to either delete some files or request additional disk space.
Recalculating Hyperlinks may fix the problem.
Your server has a default index page at /index.html. Rename or delete this page, or rename your web's index page to index.html.
This procedure fixes a number of FrontPage-related problems.
Select Tools -> Recalculate Hyperlinks and choose "Yes".
