I'm not sure when this started happening, but it's been over a year now. When I set up a website and everything seems to be working just fine. Then, all of a sudden, my FTP access to just that site stops working. I tried "Check Permissions" for the domain, and even the Plesk reconfigurator. No luck. The work around was to create a new FTP user and point them to the root directory. This fixed the FTP problem but then caused another problem. When I go to the website, it now prompts me for a login and password. When I looked at the directory permissions, I saw that the IUSR user was not in there. I added it back in and the site comes back up. Does anyone have any clue on what could be causing this to happen? The only thing I have not tried was deleting the site and adding it back in. I have this same problem on a couple other sites where this is not as easy to do with all the Database entried, emails, etc. Has anyone else come across this problem?
