It's such a long post it's hard to read.

I think that you are updating the site and your browser cache is saving the old site so you are getting a bit of a mishmash.

All browsers cache the content of pages - it speeds up your internet access. In practice web developers learn to clear the cache to view changes, or force a page refresh in the browser.

It's not something users normally see and most web developers test first then only update the main site when the design is ready.

When explaining problems, fewer words are better than a long ramble, and no, WE DON'T NEED NO CAPITALS to understand.
