If the TOC changes are showing when opened locally but not on a web server, you might be suffering from "sticky cache" (tm).
Trying clearing your browser cache, closing all browser windows and re-opening the website.
If this resolves it, try talking to your web IT guys - I'm sure there are settings that can help minimise the effect, but I don't know what they are.
Yep - I forgot about the cache. That cleared up the TOC issue. But how come the changes I made to one version of my user guide just disappeared? I saved, I did a backup, I checked the backup and the changes are there. However, the changes do not appear in RH nor in the generated output. I know I can pull up the backup, but I need to know what caused this in case it happens again.
I don't really have any suggestions on that one. I have sometimes seen changes not remembered at all if RH crashes, or sometimes if a file moves RH will remember it in the original location and it takes a bit of work to switch everything back to the old location and move them again.
The only thing is to double-check the paths to the images are correct and you don't have any duplicate (similarly named) files that you might be overlooking.
