FCP never actually fixes anything, but only either points to the appropriate forum post or the section within the OS for you to fix it.
If you're lucky, the diagnostics will show the error that you tried to fix (if the server had run a background scan, and you had FCP set to log the errors). But, you'd have to post them regardless as there's nothing else that we can help you with without knowing anything about what may or may not be going on.
