[Koha] Apache default page

[Ma. Victoria H. Silva-Manuel]

I installed Koha 18.11 on Ubuntu 16.04 LTS. I can open the staff client but
I am getting the Apache 2 default page for OPAC. I am using port 80 for
OPAC. I have tried changing the port to 81 and 8081 and delete the Apache
default page but I still cannot access the OPAC.

Any help would be appreciated.
