I have been experimenting with editing a PostNuke theme. I am having a problem that the revised web pages are not being displayed. It my efforts to customize this theme to my liking I sometime have problems were the colors that I have selected do work when I go to the admin panel (text in tabs and text boxes not visible). In those cases I often revert back to a previous theme to make some changes. I then will restore the settings to the theme that I am editing. When I did this yesterday the web site reverted back to an earlier version from several weeks ago that is not longer in the theme folder. I do not know where this older version may be hiding. I have cleaned out the cache o the computer that I working on and have meta tags on my page instructing any proxies not to cache the page.
