I'm never surprised when things are odd with software.
Anyhow, I restored the file names and there was no change. phpBB still works, but the "Forum Watch" link doesn't appear. I suspect that one of my other mods, though there aren't too many, is involved.
I've just taken a deeper dive into my files archive - I keep copies of all the mods I've installed, and of course backups of all the files they add/delete/modify (though backups of changed files do ultimately get lost in the more frequently revised files).
It seems that Category Hierarchy 2.11 is the place where the changes occur, which isn't a surprise since that mod makes major changes in how phpBB is organized. Unless someone in this group's done so already, I have to presume that the files CH uses instead of these changed viewforum files are where the problem lies. I'll have to see if I can figure out what's replaced the files and see if there's a place to add the Forum Watch code.
