Got a new machine set up with Plesk 7.5.4. Trying to connect to one or more domains on this machine with frontpage extensions enabled produces an internal server error. The only error I can find in the logs is the following: Microsoft FrontPage Server Extensions: Error #150006 Message: The FrontPage Server Extensions are not installed on '80'. I have verified that FP extensions are installed correctly and the configuration looks good. Anyone have any suggestions? Thanks!
