pgAdmin in text only

Hi there,

Trying to install PostgreSQL 9.6 and pgAdmin4 on Centos 7 for lab testing purposes but some these is the web interface that I am getting at for localhost/pgadmin4.  I believe I was to display it properly last two weeks ago but since V4.7 this is the display that I am getting at.  I saw something similar in the FAQ (https://www.pgadmin.org/faq/#6) but it’s for Windows only.  Any idea what I am missing? The command I use is sudo yum -y install epel-release followed by sudo yum -y install pgadmin4

Thanks,

Jeffrey
