I'd rather not give out my blog URL in here if you don't mind.
Not at all, I understand. It makes it easier to see the HTML but let's go around that.
Do you have two browsers installed? For example, Firefox and Internet Explorer? I'm asking because I'd like you to do the following:
1. Clear out the cache, cookies, and browsing history on both browsers.
2. Login via Firefox to your blog and delete the cache from the WP Super Cache admin page.
3. Now in Firefox view your blog posts.
4. Look at your wp-content/cache directory with the command line
ls -lt | more and check that new wp-cache-* files are being created with a time stamp around now.
5. Now in Internet Explorer go to the blog. Don't log in, just act like any plain user.
6. Look at a post in Internet Explorer and then reload it again with CTRL-F5.
7. In Internet Explorer view the source of that page and let us know if you see any
<!-- WP Super Cache --> comments.
8. See if any static HTML is in wp-content/cache/supercache. You can see that in UNIX via going to the wp-content/cache directory and running this command
find . -type f
It's a lot but this is just to see if the files are being created.
If they are but you are not seeing the files, can you check that your .htaccess is updated and that you are using fancy permalinks?
