I may have found a clue to this mystery. Last week, before the latest upgrade, I observed that in the WA page creation system, there was a list of which pages were already created so that you couldn't select a page type that was already done. In this version, I don't see that presentation. However, when attempting to redo something already created, a warning is posted.
I thought of this when I went to create a search page before I had created a results page. When the directions said to cancel the search in order to create a results first, I saw both search and results listed as pages (in the WA management system). That is what triggered my memory of how it worked on the previous, pre-CS6 upgrade.
Last week, I was able, albeit painfully, to create results pages. This was before the CS6 upgrade.
I hope this observation helps in tracking down what is going on.
Another piece of information: this domain is already being served by the earlier version of DataAssist, but since it is all contained in other folders, it shouldn't be a factor.
I reinstalled DBridge, and started a second set of pages (different table) in the test admin. Nothing has changed.
I await further guidance. Thank you.
