Possibilities:
1) Your host may be using a proxy which means new content will not display right away (can't do anything except wait if this is the problem).
2) you are seeing what is in your browser cache. Press CTRL + F5 to force a page reload.
3) you may have the wrong settings in your remote publish profile. Ask your web host for upload details. Most hosts have tutorials on how to set up FTP connections. Here is mine (
DO NOT USE THESE SETTINGS as you are not one of my hosting clients)

If all of this does not clear up your problem remove the work files and do a full remote publish. See this page for details
