Your debug log looks normal, showing your Pi-hole to be fully operational, receiving, filtering and answering DNS:

It also shows you've replaced Pi-hole's webserver lighttpd with apache2.

Your observation may be related to disallowing or incorrectly handling session cookies, either in your client browser or in your chosen webserver.

[rkstreet]

I did not know I was replacing the browser, but from what I understood Apache2 was causing the issues.

The issue started right after I installed pihole. I would think putting Apache2 back would just continue with the issue.

What should I look for with regard to session cookies?

BTW I really like this solution and I donated;

[DanSchaper]

Sessions are cookie based. If you are running a browser add on that blocks cookies or deletes them then you will have problems like you are seeing.

[rkstreet]

Thank you. I will look at that.
