Thank you.
I previously added a separate entry for wp. However, I double checked that based on your response and realized that I added it as
<Directory /var/www/wp/>
rather than /var/www/html/wp.
As of now, I don’t see any reason to restrict allowoverride to just wp, so I removed that entry and modified the primary entry for /var/www and it is working now.
Thank you very much. I’m very new and green to both Linux and Apache. It is frustrating to spend so much time trying to fix something when the solution was so simple. But, I learn more from resolving issues than I do from setting up stuff that “just works”. ??
