Just to follow-up and close this one out, I did get WPFixit involved, shared your info, and they were able to add something to the .htaccess file that straightened it out. Thanks for your help.
Well crapola. I finally gave up on this and restored from backup I made prior to updating to latest WP version and updating all the plugins and the issue is still there. I will take this info and try to find someone to fix this. thx.
Here is the error I get:
