Thank you for continuing to think about potential causes of this problem.

I'm still looking at the peculiar similarity of the actual versus desired destination when the problem does manifest.  See my post #13 above.  It seems to me that it might be a situation where rewrite rules are indeed always in effect but not necessarily in the desired sequence. 

For example, if a "non-Simple:Press" rule gets matched before a "Simple:Press" rule, it would map to the Unit page.  This would be the undesired "problem" scenario.  This happens when Simple:Press Update WP Integration is NOT done AFTER the automatic flushing of rewrite rules that occurs when the Settings>Permalinks page is viewed

If, on the other hand, the "Simple:Press" rule matches first, it would map to the Forum page.  This would be the desired "no problem" scenario.  This happens when Simple:Press Update WP Integration IS done AFTER the automatic flushing of rewrite rules that occurs when the Settings>Permalinks page is viewed.

If this is the explanation, then changing the Unit page slugs so as not to conflict with the Forum page slugs should resolve the problem.  I'll try this and let you know what I find.

Success!

The problem was apparently related to a conflict between slugs.

My Units (which were in fact posts, not pages) were set up with slugs that were identical to the slugs used by the Forums for those Units.

I didn't realize that slugs need to be globally unique across all post types, including Forums.  Now I know better.

Perhaps some additional uniqueness validation could be done in the Simple:Press code to make sure that another user doesn't follow in my unwitting footsteps by creating a non-unique slug for a Forum.

I think it was a case of the "non-Simple:Press" rule matching the slug first, then sending to the post URL.  The "Simple:Press" rule was never run because the other rule matched first.  When the SP Update WP Integration is done, it puts the "Simple:Press" rule before the "non-Simple:Press" rule, causing the slug to subsequently match the "Simple:Press" rule first, sending to the forum URL.

And yes, the "index.php" is indeed always present in the URLs.

Enforcing unique slugs should prevent the problem in any case.

I'm using "Month and name" structure:

To create the same scenario as I had, you would want to

1. create a post with the slug "dupe-slug"

2. create a forum with the slug "dupe-slug"

3. create a page with a link to the forum in #2.

4. View the Permalink Settings.

5. View the page in #3, then click the link to the forum.  You should land instead at the post in #1.

6. Update WP Integration.

7. Repeat #5. You should land at the forum as desired. (Until you next view the Permalink Settings.)

Great!  I'm glad we persevered to a successful conclusion.
