Takayuki Miyoshi: I disabled the two BestWebSoft plugins. It had no affect.
davmerit: I re saved the Options-Permalink.php file in WP Admin. No joy with that change either.
Thank you both for responding! I really appreciate it. It you have any other ideas, I ready to try anything. I confess, I'm about to burn the site to the ground, remove WordPress and re-install, then start putting everything back up without copying and pasting anything to avoid reintroducing the problem.
Thanks again
