Here are some images. I created a new project with just a few topics to make certain the original project hadn't gone corrupt. Then I applied the conditional tag to one topic.
The Topic Properties screen shows the tag is checked.
I also applied the conditional tag from the TOC by right-clicking the topic, so it was indicated in both places.
The topic has slashes to indicate I applied conditional tags:
I published to the server that should NOT display the conditional tag. I tried it both ways, clicking and unclicking Check for Deleted Files and Republish All. It has no effect on the output.
The topic still displays.
Have I missed anything? Does Adobe publish automatic updates? Is it possible I received a patch or an update of some kind that broke the conditional tags? Like I said, the older version, uploaded to a different directory, has conditional tags that work. I just can't make them work anymore.
Thank you so much! That was it! I hadn't done this in a while, and totally forgot that step. Yay!
