Often when I go to update the website with FTB by clicking on the "Publish" button, I get a message to the effect that the version on the website is newer than the version I'm trying to upload, do I want to continue. I know for a fact that this not true just by virtue of timestamps & having just entered new info. I figured out a workaround, but this should not be necessary. The workaround is to go to "Tools," "Publishing Settings," delete any projects that are listed, add a new project (actually just the current project you want to upload/update) & then proceed as if it's a new project. Make sure to login using the link to "Sign in as a different member." This has turned out to be the only reliable way I can update my site. Sounds like a bug to me.
Thanks for the suggestion, Jim. However, my computer's clock syncs with the U.S. Naval Observatory's atomic clock, so the date/time on my computer are always correct.
