Can't Change Forum URL

Do you mean this setting is reverting somehow?

Admin CP -> Home -> Options -> Basic Board Information -> Board URL

Does it save in the first place? Try changing the setting and saving it, then revisit the page to ensure it has updated.
 
Then there must be a problem with the server. Perhaps some kind of save point / restore system that is being triggered on restart. You should contact your host or server person about this.
